Question

Should the value of escape velocity be less or more in the surface of Moon as compared to Earth ?

Answer 1

The formula of $P$ escape velocity :- $V=\sqrt{2gR}$

The escape velocity depends on the radius of the earth and the moon as well as the gravitational acceleration of the earth as well as moon. So, gravitational force of the earth is greater than gravitational force of the moon. Besides, the radius of the earth is greater than radius of the moon.

So, The value of escape velocity be less in the surface of moon as compared to earth.
