The radii of two planets are respectively `R_(1) and R_(2)` and their densities are respectively `rho_(1) and rho_(2)`.The ratio of the accelerations due to gravity at their surface is

Options

A. `g_(1):g_(2) = (rho_(1))/(R_(1)^(2)) : (rho_(2))/(R_(2)^(2))`
B. `g_(1) : g_(2) = R_(1) R_(2) : rho_(1) rho_(2)`
C. `g_(1) : g_(1) = R_(1) rho_(2) : R_(2) rho_(1)`
D. `g_(1) : g_(2) = R_(1) rho_(1) : R_(2) rho_(2)`

Answer

D
