There are two planets. The ratio of radius of two planets is `k` but radio of acceleration due to gravity of both planets is g. What will be the ratio of their escape velocity ?

A

`(kg)^(1//2)`

B

`(kg)^(-1//2)`

C

`(kg)^(2)`

D

`(kg)^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`nu_(e) = sqrt(2gR)`
or `nu_(e) prop sqrt(gR)`
