PhysicsNEET 2019Gravitational potential and potential energy

Gravitation

The work done to raise a mass mm from the surface of the earth to a height hh, equal to the radius of the earth, is:

  1. A.mgRmgR
  2. B.2mgR2mgR
  3. C.12mgR\dfrac{1}{2}mgR✓
  4. D.32mgR\dfrac{3}{2}mgR

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
