The work done to raise a mass m from the surface of the earth to a height h, which is equal to the radius of the earth, is :

The amount of work done in lifting a body of mass 'm' from the surface of the earth to a height equal to twice the radius of the earth is,

The work done to take a particle of mass m from surface of the earth to a height equal to 2R is

If g is the acceleration due to gravity on the earth’s surface, the gain in the potential energy of an QBject of mass m raised from the surface of the earth to a height equal to the radius R of the earth is :

If g be the acceleration due to gravity of the earth's surface, the gain is the potential energy of an object of mass m raised from the surface of the earth to a height equal to the radius R of the earth is

If g is the acceleration due to gravity on earth's surface, the gain of the potential energy of an object of mass m raised from the surface of the earth to a height equal to the radius R of the earth is
