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 surfaces is

Question

Accepted Answer

${g_1}:{g_2} = {R_1}{\rho _1}:{R_2}{\rho _2}$

Answer

${g_1}:{g_2} = \frac{{{\rho _1}}}{{R_1^2}}:\frac{{{\rho _2}}}{{R_2^2}}$

Answer

${g_1}:{g_2} = {R_1}{R_2}:{\rho _1}{\rho _2}$

Answer

${g_1}:{g_2} = {R_1}{\rho _2}:{R_2}{\rho _1}$
