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 body of mass m has to be taken from the surface to the earth to a height h=4R , then the amount of energy required is (R = radius of the earth)

If body of mass m has to be taken from the surface to the earth to a height h=4R , then the amount of energy required is (R = radius of the earth)

What will be the gain in 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 ?

If .g. is acceleration due to gravity on the earth.s surface, then the gain in PE 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

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 ?
