The increase in gravitational potential energy of an object of mass $m$ raised from the surface of Earth to a height equal to radius $R$ of Earth is -

Options:

Answer:

Solution:

Increase in potential energy

$= \frac{- G M m}{2 R} - (\frac{- G M m}{R}) = \frac{G m M}{2 R} = \frac{G M}{R^{2}} \times \frac{m R}{2}$

$= g \times \frac{1}{2} m R = \frac{1}{2} m g R$
