Gravitation

Question: 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

1) $\frac{R}{r}\frac{{{\rho _e}}}{{{\rho _m}}}$

2) $\frac{r}{R}\frac{{{\rho _e}}}{{{\rho _m}}}$

3) $\frac{r}{R}\frac{{{\rho _m}}}{{{\rho _e}}}$

4) $\frac{R}{r}\frac{{{\rho _e}}}{{{\rho _m}}}$
