Dr. S K Jain and Dr. Shailesh K Jain Solutions for Chapter: Gravitation, Exercise 2: Class Assignment 2

Why is the weight of an object on the moon $\frac{1}{6}\mathrm{th}$  its weight on the earth?

Gravitational force acts on all objects in proportion to their masses. Then why does a heavier object not fall faster than the lighter object?

What happens to the force between two objects, if the mass of one object is doubled?

What happens to the force between two objects, if the distance between the objects is doubled?

What happens to the force between two objects, if the masses of both the objects are doubled?

Two objects of different masses falling freely near the surface of the moon would 

The atmosphere is held to the earth by

The weight of an object at the centre of the earth of radius $\mathrm{R}$ is
