If $g$ is the acceleration due to gravity on the surface of the earth, the gain in potential energy of an object of mass $m$ raised from the earth's surface to a height equal to the radius $R$ of the earth is

Options:

Answer:

Solution:

Hints: $Δ U = \frac{mgh}{1 + \frac{h}{R}} = \frac{mgR}{1 + \frac{R}{R}} = \frac{mgR}{2}$
