Question

A mass m on the surface of the Earth is shifted to a target equal to the radius of the Earth. If R is the radius and M is the mass of the Earth, then work done in this process is, m g R 2, m g R, 2 m g R, m g R 4

MARKS App · Accepted Answer

Work done = ∆ P E = - G M m R + R - - G M m R = G M m 2 R = m g R 2
