A mass is raised from the surface of the earth to a point which is at a height pR from the centre of the earth, where r is the radius of the earth. Calculation the chagne P.E. If the lifted mass is to be made an artificial satellite of the earth at that distacnce, what is the total work done? Acceleration due to gravity at the suraface of the earth is g.
