R and r are the radii of the earth and moon respectively. \[{{\rho }_{e}}\] and \[{{\rho }_{m}}\] are the densities of earth and moon respectively. The ratio of the accelerations due to gravity on the surfaces of earth and moon is [EAMCET 2000]

\[\frac{r}{R}\frac{{{\rho }_{e}}}{{{\rho }_{m}}}\]

\[\frac{R}{r}\frac{{{\rho }_{e}}}{{{\rho }_{m}}}\]

\[\frac{r}{R}\frac{{{\rho }_{m}}}{{{\rho }_{e}}}\]

\[\frac{R}{r}\frac{{{\rho }_{e}}}{{{\rho }_{m}}}\]

R and r are the radii of the earth and moon respectively. \[{{\rho }_{
