The best part of HC Verma book is that the concepts of modern physics and mechanics part are described in such a manner that an average student can also understand basics concepts in an easy way and can solve large varieties of questions after understanding the solved example given by HC Verma in concepts of the physics book.

Concepts of Physics by HC Verma book is written by understanding the requirements of students from India. There are almost all varieties of questions you can find in HCV. Even the objective questions are also available which helps the candidate to test their chapter insight knowledge and help them to improve it.

The concepts are given in a succinct and in a format to make it very easy to hold. Many new books claimed that they have better than stuff than concepts of physics. There have been instances when questions are asked directly from the book Concept of physics. Physics is an immeasurable Subject and It is a difficult task to bound entire physics in 2 books with proper explanation of each and every topic. Find the retardation of the ball is sand assuming it to be uniform.

A ball is dropped from a height of 5 m s above the sand level. The same ball penetrates the sand up to 10 cm s s before coming to rest. Velocity of the ball after 1. An elevator is descending with uniform acceleration. To measure the acceleration, a person in the elevator drops a coin at the moment the elevator starts. The coin is 6 ft above the floor of the elevator at the time it is dropped.

The person observes that the coin strikes the floor in 1 second. Calculate from these data the acceleration of the elevator.

It is given that the coin reaches the floor in 1 second. This means that the coin travels 6 ft distance.

Equation for the coin: Find a the time it takes to reach the ground, b the horizontal distance it travels before reaching the ground, c the velocity direction and magnitude with which it strikes the ground. Using the equation of motion, we have: Find a the maximum height reached and b the range of the ball. In a soccer practice session the football is kept at the centre of the filed 40 yards from the 10 ft high goalposts. Will the ball reach the goal post? A popular game in Indian villages is goli which is played with small glass balls called golis.

The goli of one player is situated at a distance of 2. This second player has to project his goli by keeping the thumb of the left hand at the place of his goli, holding the goli between his two middle fingers and making the throw. If the projected goli hits the goli of the first player, the second player wins. If the height from which the goli is projected is As the initial velocity u y in vertical direction is zero, we have: With what minimum speed should a motorbike be moving on the road so that it safely crosses the ditch?

Figure Assume that the length of the bike is 5 ft, and it leaves the road when the front part runs out of the approach road. A person standing on the top of a cliff ft high has to throw a packet to his friend standing on the ground ft horizontally away.

If he throws the packet directly aiming at the friend with a speed of From the diagram, we can write: Let us take the reference axis at point A.

Will it hit a vertical wall 5 m away from the point of projection and perpendicular to the plane of projection without hitting the floor? Will the answer differ if the wall is 22 m away? If the wall is 22 m away from the point of projection, the ball will hit the wall because it is not in its horizontal range.

Find the average velocity of a projectile between the instants it crosses half the maximum height. By the symmetry of figure, it can be said that the line joining points A and B is horizontal. So, there will be no effect of the vertical component of velocity of the projectile during displacement AB. A bomb is dropped from a plane flying horizontally with uniform speed. Show that the bomb will explode vertically below the plane. Is the statement true if the plane flies with uniform speed but not horizontally?

The plane is flying horizontally with a uniform speed. Therefore, the bomb also has the same speed. Let the speed of the plane be represented by u. Now, let t be the time taken by the bomb to reach the ground.

So, both the plane and the bomb will be flying with the same angle of projection. When the bomb is released, the time taken by the bomb to reach the ground is t. Hence, again the bomb will explode vertically below the plane. Let the bomb reach the ground in time t.

So, the bomb will explode vertically below the plane. A boy standing on a long railroad car throws a ball straight upwards. How far behind the boy will the ball fall on the car?

Both the car and the ball have the same horizontal velocity. What should be the minimum horizontal velocity of a ball rolling of the uppermost plane so as to hit directly the lowest plane? Let point A be the origin of reference coordinate.

Let u be the minimum speed of the ball. A person is standing on a truck moving with a constant velocity of The man throws a ball in such a way that it returns to the truck after the truck has moved Find the speed and the angle of projection a as seen from the truck, b as seen from the road. Time in which the truck has moved the distance of Thus, we get: The benches of a gallery in a cricket stadium are 1 m wide and 1 m high.

A batsman strikes the ball at a level one metre above the ground and hits a mammoth sixer. The benches are perpendicular to the plane of motion and the first bench is m from the batsman. On which bench will the ball hit? Let the ball land on the n th bench. A man is sitting on the shore of a river.

He is in the line of 1. He wishes to throw an apple into the boat. Assume that the point of projection and the edge of the boat are in the same horizontal level. A river m wide is flowing at a rate of 2. The boat sails at the resultant velocity v r. Time taken by the boat to reach the opposite shore: Consider the situation of the previous problem.

The man has to reach the other shore at the point directly opposite to his starting point. If he reaches the other shore somewhere else, he has to walk down to this point. Find the minimum distance that he has to walk. From Horizontal distance is BD for the resultant velocity v r. Two friends A and B are standing a distance x apart in an open field and wind is blowing from A to B.

A beat a drum and B hears the sound t 1 time after he sees the event. A and B interchange their positions and the experiment is repeated.

This time B hears the drum timer after he sees the event. Calculate the velocity of sound in still air v and the velocity of wind u.

Neglect the time light takes in travelling between the friends. When A beats the drum from his original position: After interchanging the positions: Suppose A and B in the previous problem change their positions in such a way that the line joining them becomes perpendicular to the direction of wind while maintaining the separation x.

What will be the time B finds between seeing and hearing the drum beating by A? Let u be the velocity of air in the direction along line AB. Six particles situated at the corner of a regular hexagon of side a move at a constant speed v. Each particle maintains a direction towards the particle at the next corner. Calculate the time the particles will take to meet each other. A regular hexagon has a side a.

## HC Verma Class 11 Physics Part-1 Solutions for Chapter 3 - Rest and Motion Kinematics

Six particles situated at the corners of the hexagon are moving with a constant speed v. As per the question, each particle maintains a direction towards the particle at the next corner.

So, particles will meet at centroid O of triangle PQR. Now, at any instant, the particles will form an equilateral triangle PQR with the same centroid O.

We know that P approaches Q, Q approaches R and so on.

Now, we will consider the motion of particle P. This component is the rate of decrease of distance PO. Relative velocity between P and Q: So the ball will hit the wall. In second case 22 m away wall is not within the horizontal range.

So the ball would not hit the wall. So there is no effect of vertical component of the velocity during this displacement. Show that the bomb will explode vertically below the plane. Is the statement true if the plane flies with uniform speed but not horizontally? Suppose the bomb explode i.

How far behind the boy will the ball fall on the car? Let the velocity of car be u when the all is thrown. What should be the minimum horizontal velocity of a ball rolling off the uppermost plane so as to hit directly the lowest plane? At minimum velocity it will move just touching point E reaching the ground.

Taking vertical component of velocity into consideration. A batsman strikes the ball at a level one metre above the ground and hits a mammoth sixer. On which bench will the ball hit? From the equation , y can be calculated.

He wishes to throw an apple into the boat.The balloon and the ball are moving upwards with the same speed. He should swim in a direction. With what minimum speed should a motorbike be moving on the road so that it safely crosses the ditch? So, he will take more time. Find the time taken during the retardation. Hence, the average speed will not be zero. Question 8:
