Potential energy of a 3kg body at the surface of a planet is `-54 J`, then escape velocity will be :

The mass and diameter of a planet are half of thast of the earth. The ratio of gravitational potential energy of a body on the surface of the planet to that on the surface of the earth is

What is the gravitational potential energy (MJ) of a body of mass 3 kg on a planet where escape velocity is 4 km s^(-1) ?

If the gravitational potential energy of a body on a planet is numerically equal to . U and the escape velocity of the same body is V_(e') then

The escape velocity of a body from the surface of earth is

Gas escapes from the surface of a planet because it acquires an escape velocity. The escape velocity will depend on which of the following factors: (1) Mass of the planet (2) Radius of the planet (3) Mass of the particle escaping (4) Temperature of the planet
