The potential energy of a body of mass $3 k g$ on the surface of a planet is $54 j o u l e$ . The escape velocity will be

Options:

Answer:

Solution:

$U_{i n i t i a l} + K_{i n i t i a l} = U_{F i n a l} + K_{F i n a l}$

$\frac{1}{2} m v_{e}^{2} = \frac{G M m}{R}$

$\frac{1}{2} (3) v_{e}^{2} = 54$

$v_{e} = 6 m / s$
