Acceleration due to gravity on a planet ...

Acceleration due to gravity on a planet is 10 times the value on the earth. Escape velocity for the planet and the earth are `V_(p)` and `V_(e)` respectively. Assuming that the radii of the planet and the earth are the same, then -

A

`V_(P) = 10 V_(e)`

B

`V_(P) = sqrt10 V_(e)`

C

`V_(P) = (V_(e))/(sqrt10)`

D

`V_(P) = (V_(e))/(10)`
