The escape velocity of an object on a planet whose radius is 4 times that of the earth and value of g is same as that on the earth , in `km-s^-1` is

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 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 value of the escape velocity from the earth is v_e . If the radius of a planet is 4 times that of the earth and its density is 9 times the density of the earth, then the value of the escape velocity from that planet will be

If the radius of a planet is four times that of earth and the value of g is same for both, the escape velocity on the planet will be
