If W₁, W₂ and W₃ represent the work done in moving a particle from A to B along three different paths 1, 2 and 3 respectively (as shown) in a gravitational field of point mass m, then

Suppose the gravitational force varies inversely as the nth power of distance. Then, the time period of a planet in circular orbit of radius R around the sun will be proportional to

The change in the value of ‘g’ at a height ‘h’ above the surface of the earth is the same as at a depth ‘d’ below the surface of earth. When both ‘d’ and ‘h’ are much smaller than the radius of earth, then which one of the following is correct ?

The correct graph representing the variation of total energy (ET), kinetic energy (EK) and potential energy (EP) of a satellite with its distance (r) from the centre of earth is

Two identical solid copper spheres of radius R are placed in contact with each other. The gravitational force between them is proportional to

The gravitational force Fg between two objects does not depend on

The atmosphere is held to the earth by

Two sphere of mass m₁ and m₂ are situated in air and the gravitational force between them is F. The space around the masses is now filled with liquid of specific gravity 3. The gravitational force will now be

A satellite of the earth is revolving in a circular orbit with a uniform speed v. If the gravitational force suddenly disappears, the satellite will
