Two planets have same density but different radii The acceleration due to gravity would be .

Two planets have same density but different raddi. The acceleration due to gravity would be

If different planets have the same density but diferent radii then the acceleration due to gravity (g) on the surface of the planet will depend on its radius (R) as

Two planets have the same average density but their radii are R_(1) and R_(2) . If acceleration due to gravity on these planets be g_(1) and g_(2) respectively, then

A planet has same density and same acceleration due to gravity as of earth and universal gravitational constant G is twice of earth. The ratio of their radii is

Two planets A and B have their radii in the ratio r. The ratio of acceleration due to gravity on the planets is x. what is the ratio of the escape velocity from the two planets ?
