1.	Two planets if radii in the ratio 2:3 are made from the material of density in the ratio 3:2. Then the ratio of acceleration due to gravity at the surface of the two planets will be ...........
Answer» `1:1` `2:25:1` `4:9` `0:12:1` SOLUTION :`IMPLIES` ACCORDING to G ` = (4/2 piGRrho)` `g_1/g_2=(R_1rho_1)/(R_2rho_2)=((R_1)/(R_2))((rho_1)/(rho_2))=(2/3)(3/2)=1/1` `g_1/g_2 = 1:1`
