The acceleration due to gravity on the moon is one-sixth that on earth. If the average density of moon is three-fifth that of earth, the moon's radius in terms of earth's radius `R_(e)` is -

A

`0.16R_(e)`

B

`0.27R_(e)`

C

`0.32R_(e)`

D

`0.36R_(e)`

Text Solution

Verified by Experts

The correct Answer is:
B
`g prop R rho`
`(R_(m))/(R_(e))=(g_(m))/(g_(e))(rho_(e))/(rho_(m))=(1)/(6)xx(5)/(3)`
