Answer:

The below is your answer . Hope it helps you :)

Explanation:

From work-energy theorem, work done = change in potential energy.

Work done = ∫R3Rx2GmMdx=3R2GmM=32mgR.

Please note that the gravitational force will necessarily vary over this height because it is comparable with earth's radius.
