The escape velocity of an object on a planet whose radius is `4` times that of the earth and `g` value `9` tims that on the earth, in `Kms^(-1)`, is

" The escape velocity (in km/s) of a planet whose acceleration due to gravity is "10" times that on the earth and radius "5" times that of the earth "

The escape velocity of a planet having mass 6 times and radius 2 times as those of the earth is

The escape velocity for the earth is v_(e) . The escape velocity for a planet whose radius is four times and density is nine times that of the earth, is

If the escape velocity of a planet is 3 times that of the earth and its radius is 4 times that of the earth, then the mass of the planet is (Mass of the earth = 6 xx 10^24 kg )

The escape velocity of a body on an imaginary planet which is thrice the radius of the earth and double the mass of the earth is ( v_(e) is the escape velocity of earth)

The escape velocity of a body on the surface of the earth is V_(e) . What is the escape velocity on a planet whose radius is thrice the radius of the earth and whose mass is double the mass of the earth?

Escape velocity on the surface of earth is 11.2 km/s . Escape velocity from a planet whose mass is the same as that of earth and radius 1/4 that of earth is
