Answer:
mgh
Explanation:
At the surface of the earth h(height of elevation) is 0. The expression for gravitational potential energy = mgh.
m×g×0=0.
Therefore, at height 'H' the gravitational potential energy of the body of mass 'm' will be mgh.
Hope this is helpful.

Answer:
mgh-Eo
Explanation:
we calculate change in gravitartional potential energy
♡U = mgh ÷ ( 1+ h/R )
this is the actual formula to calculate change in gravitational potential energy
Since h is considered as small value in comparision to R in the given problem so we choose it as mgh
Ufinal - U initial = mgh
Ufinal = mgh + U initial
Ufinal = mgh + Eo
hope you found it helpful mate !+!
