The spherical planets have the same mass but densities in the ratio `1: 8`. For these planets the :

Two spherical planets have the same mass but densities in the ratio 1:8. For these planets, the (a) acceleration due to gravity will be in the ratio 4:1 (b) acceleration due to gravity will be in the ratio 1:4 c) escape velocities from their surfaces will be in the ratio sqrt2:1 d) escape velocities from their surfaces will be in the ratio 1:sqrt2

The masses of two planets are in the ratio 1:2 their radii are in the ratio 1:2. Find the ratio of the acceleration due to gravity on the planets .

The diameters of two planets are in the ratio 4 : 1 and their mean densities in the ratio 1 : 2. The acceleration due to gravity on the planets will be in ratio

The diameters of two planets are in the ratio 4 : 1 and their mean densities in the ratio 1 : 2. The acceleration due to gravity on the planets will be in ratio

Tow spherical planet A and B have same mass but of acceleartion due to gravity at the surface of A to its value at surface of B is

Two planets are of the same material but their radii are in the ratio 2:1 . Then ratio of accelerations due to gravity on those two planets is
