 # HC Verma Solutions Vol 1 Chapter 11 Gravitation

HC Verma Solutions Vol 1 Chapter 11 Gravitation has a collection of accurate solutions for questions that are found in class 11 HC Verma textbook. Some of the questions in this chapter are related to various topics such as finding the gravitational force of attraction and linear momentum of objects when the gravitational force is acting upon them and much more. With the solutions provided, students will get to learn topics of gravitation in problems such as:

• Finding the potential energy of objects when they are separated.
• Finding the direction of the field and displacement of the particle.

Additionally, we will be seeing questions related to gravity on Mount Everest and more. However, the solutions are given for every question and it will help students to learn the right method to solve these questions and also in a better way. Making use of the solutions will not only help students in gaining conceptual clarity but it will also help them to prepare effectively for JEE. Students can clear all their doubts with respect to the topics discussed in the class 11 physics syllabus here.

Practising the problems given in solutions of HC Verma will significantly help students enhance their problem-solving skills.

Some of the topics that students will come across and study in chapter 11 are as follows;

1. Historical Introduction
2. Measurement of Gravitational Constant G
3. Gravitational Potential Energy
4. Gravitational Potential
5. Calculation of Gravitational Potential

## Important Questions In Chapter 11

1. When a spacecraft travels from the earth to the moon it consumes more fuel than coming back from the moon. Explain this phenomenon.

2. An object will have greater weight at the poles than at the equator. Do you think is it profitable to purchase goods at the equator and sell them at the pole? Do you think that using a spring balance or an equal-beam balance is necessary to be used?

3. Suppose the radius of the earth decreases by 1 per cent but there is no change in its mass. What will happen to the acceleration due to gravity at the surface of the earth? Will it increase or decrease and by what per cent?

4. Let’s bring a mass of 1 kg from infinity to a point A. Initially, the mass was at rest but it then moves at a speed of 2 m/s to reach point A. The work done on the mass is 3 J. Determine the potential at A.

(a) —5 J/kg (b) —2 J/kg (c) —3 J/kg (d) none of these.

5. If we consider the magnitude of the gravitational potential energy of the moon-earth system as U with zero potential energy at infinite separation and the kinetic energy of the moon with respect to the earth is K. Choose the right option;

(a) U = K. (b) U > K. (c) U < K.
