Average densities of two planets is same...

Average densities of two planets is same but their radii are `R_1 and R_2`. If the acceleration of gravity on planets are `g_1 and g_2` respectively, then

A

`g_1/(g_2 )= R_1/R_2`

B

`g_1/(g_2) = R_2/R_1`

C

`g_1/(g_2) = R_1^2/R_2^2`

D

`g_1/(g_2) = R_1^3/R_2^3`

Text Solution

Verified by Experts

The correct Answer is:
A
`implies` In equation `g = 4/3 pi rho ` GR , `rho` is constant
`:.g_1/ g_2 = R_1/R_2`
