The ratio of the radii of planets A and ...

The ratio of the radii of planets A and B is `k_(1)` and ratio of acceleration due to gravity on them is `k_(2)` . The ratio of escape velocities from them will be

A

`k_1k_2`

B

`sqrt(k_1k_2)`

C

`sqrt((k_1)/(k_2))`

D

`sqrt((k_2)/(k_1))`

Text Solution

Verified by Experts

The correct Answer is:
B
`(ve_1)/(ve_2)=sqrt((2g_1R_1)/(2g_2R_2))=sqrt(k_1k_2)`
