A spherical planet has a mass `M_(p)` and diameter `D_(p)`. A particle of mass m falling freely near the surface of this planet will experience an acceleration due to gravity, equal to :

A

`6GM_(p)m//D_(p)^(2)`

B

`4GM_(p)//D_(p)^(2)`

C

`GM_(p)m//D_(p)^(2)`

D

`GM_(p)//D_(p)^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`g=(GM_(p))/(R^(2))=(4GM_(p))/(D_(p)^(2))`
Thus correct choice is (b).
