If mass of earth is \( M \), radius is \( R \), and gravitational
\( \mathrm{P} \)
constant is \( G \), then work done to take \( 1 \mathrm{Kg} \) mass from earth surface to infinity will be
W
(1) \( \sqrt{\frac{G M}{2 R}} \)
(2) \( \frac{G M}{R} \)
(3) \( \sqrt{\frac{2 G M}{R}} \)
(4) \( \frac{G M}{2 R} \)
