Q2NEET 2026Easy

Gravitational Potential & Energy

The amount of work done to raise a mass ' mm ' from the surface of the Earth to a height equal to the radius of the Earth ' RR ' will be

Show answer and solution

Answer: (d)

  1. W=ΔU=mgh1+hRW = \Delta U = \frac{mgh}{1+\frac{h}{R}}
  2. With h=Rh = R: W=mgR2W = \frac{mgR}{2}
  3. So the answer is (d) mgR2mg\frac{R}{2}.
