A) mass of body
B) mass of earth
C) speed of light
D) angle of projection
Correct Answer: B
Solution :
Escape velocity of body is \[\upsilon {{ & }_{es}}=\sqrt{\frac{G{{M}_{e}}}{{{R}_{e}}}}\] Hence, escape velocity is independent of mass of body, speed of light and angle of projection, so, choices (a), (c) and (d) are wrong. From (1), escape velocity depends on mass and radius of earth so, choice (b) is correct.
