An object of mass `m` is raised from the surface of the earth to a height equal to the radius of the earth, that is, taken from a distance R to 2R from the centre of the earth. What is the gain in its potential energy ?

If 'g' 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

A body of mass m is raised from the surface of the earth up to a height equal to the radius R of the earth. If the acceleration due to gravity on the earth's surface is g , prove that the potential energy of the body has increased by 1/2 mgR.

If an object of mass m is taken from the surface of earth (radius R) to a height 5R, then the work done is

If an object of mass m is taken from the surface of earth (radius R) to a height 5R, then the work done is

A body of mass m is taken from the Earth's surface to a height equal to the radius R of the earth. If g is the acceleration to gravity at the surface of the Earth, then find the change in the potential energy of the body .......

A body of mass m is taken from earth surface to the height h equal to radius of earth, the increase in potential energy will be

A body of mass m is taken from earth surface to the height h equal to radius of earth, the increase in potential energy will be

A body of mass m is lifted from the surface of earth of height equal to R//3 where R is the radius of earth, potential energy of the body increases by
