What does your textbook say about G M m?
/ ( . ) By using Binomial expansion and neglecting the higher order terms, we get U G M m h e e e = − ( . ) We know that, for a mass m on the Earth’s surface, G M m mgR e e e ( . ) Substituting equation ( . ) in ( . ) we get, U mgR mgh e ( . ) It is clear that the first term in the above expression is independent of the height h. For example, if the object is taken from separated by an infinite distance and by distance r. U r U r U . Here we choose U = as the reference point.
