Answer 1

GMm/R is the increase in potential energy

Answer 2

A body of mass 'm' is moved to a height 'h' equal to the radius of earth. What is the increase in potential energy?

What does Google know about me?

Firstly, from where is the body being moved and where?

Assuming it is lifted (radially outward) from the surface of the earth considering only the gravitational fields of the body and the earth,

Change in P.E.= (G.m.M/R)-(G.m.M/2R)

= G.m.M/2R

G = universal gravitational constant

m= mass of body in consideration

M= mass of earth

R= radius of earth

The term 2R in second term comes as follows: r'=R+h=2R (h=R in this case).
