PhysicsNEET 2020Newton's law of gravitation, g and its variation

Gravitation

A body weighs 72 N on the surface of the earth. What is the gravitational force on it at a height equal to half the radius of the earth?

  1. A.48 N
  2. B.32 N✓
  3. C.30 N
  4. D.24 N

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