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)

If mass of planet is eight times the mass of the earth and its radius is twice the radius of the earth, what will be the escape velocity for that planet?

The mass of (an imaginary) planet is four times that of the earth and its radius is double the radius of the earth. The escape velocity of a body from the earth is 11.2xx10^(3)m//s . Find the escape velocity of a body from the planet.

If the mass of a Planet is eight times the mass of the earth and its radius is twice the radius of the earth, what will be the escape velocity for that planet ?

The escape velocity of a body from the earth is V_(e) if the radius of earth contracts to 1//4 th of its value keeping the mass of the earth constant the escape velocity will be

The escape velocity of a body from the surface of the earth is V_(1) and from an altitude equal to twice the radius of the earth, is, V_(2) . Then
