Give the relation between Kc and Delta G

Two planets A and B have the same average density . Their radii R_A and R_B are such that R_A: R_B = 3 : 1 . If g_A and g_B are the acceleration due to gravity at the surface of the planets , the g_A : g_B equals

The mass of a planet and its diameter are three times those of earth's. Then the acceleration due to gravity on the surface of the planet is : (g =9.8 ms^(-2))

Find the relation between the gravitational field on the surface of two planets A and B of masses m_(A), m_(B) and radii R_(A) and R_(B), respectively if a. they have equal mass. b. they have equal (uniform)density.

Two planets A and B have the same averge density . Their radii R_A and R_B are such that R_A : R_B = 3 : 1 . If g_A and g_B are the acceleration due to gravity at the surfaces of the planets, the g_A : g_B equals

g_(e) and g_(p) denote the acceleration due to gravity on the surface of the earth and another planet whose mass and radius are twice as that of earth. Then

The density of a newly discovered planet is twice that of earth. The acceleration due to gravity at the surface of the planet is equal to that at the surface of the earth. If the radius of the earth is R , the radius of the planet would be

If g_(1) and g_(2) denote acceleration due to gravity on the surface of the earth and on a planet whose mass and radius is thrice that of earth, then

What will be the relation between the acceleration due to gravity on the surface of the earth and on a planet respectively, whose mass and radius are four times that of the earth ?

In a hypothetical uniform and spherical planet of mass M and radius R , a tunel is dug radiay from its surface to its centre as shown. The minimum energy required to carry a unit mass from its centre to the surface is kmgR. Find value of k . Acceleration due to gravity at the surface of the planet is g .
