Let the minimum external work done in shifted a particle form centre of earth to earth's surface be `W_(1)` and that form surface of earth to infinity be `W_(2)` . Then `(W_(1))/(W_(2))` is equl to

The work done liftting a particle of mass 'm' from the centre of the earth to the surface of the earth is

What is the work done in shifting a body of mass m=5okg slowly from the earth's surface to infinity?

What is the work done in shifting a body of mass m=5okg slowly from the earth's surface to infinity?

Find work done in shifting a body of mass m from a height h above the earth's surface to a height 2h above the earth's surface.

Find work done in shifting a body of mass m from a height h above the earth's surface to a height 2h above the earth's surface..

Assertion : Let W_(1) be the work done in taking away a satellite from the surface of earth to its orbit and then W_(2) the work done in rotating the satellite in circular orbit there. Then, W_(1)=W_(2) Reason : W_(2)=(GMm)/(4R)
