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_2respectively, then

Average densities of two planets is same but their radii are R_1 and R

1.	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_2respectively, then
Answer» `g_1/(g_2 )= R_1/R_2` `g_1/(g_2) = R_2/R_1` `g_1/(g_2) = R_1^2/R_2^2` `g_1/(g_2) = R_1^3/R_2^3` SOLUTION :`IMPLIES` In equation `G = 4/3 pi rho ` GR , `rho` is constant `:.g_1/ g_2 = R_1/R_2`
