A) \[\sqrt{\frac{2R{{M}_{e}}}{{{R}_{e}}}}\]
B) \[\sqrt{\frac{2G{{M}_{e}}m}{{{R}_{e}}}}\]
C) \[\sqrt{\frac{G{{M}_{e}}}{{{R}_{e}}}}\]
D) \[\sqrt{\frac{GM}{{{R}_{e}}}}\]
Correct Answer: A
Solution :
Escape velocity of a body, from the surfaces of earth \[{{v}_{e}}=\sqrt{\frac{2G{{M}_{e}}}{{{R}_{e}}}}\] It does not depend on the mass of the body.
