Gravitational Potential At A Point Due To The Earth

What is the relation between gravitational intensity and gravitational potential at a point?

If the gravitational potential energy of a body at a distance r from the centre of the earth is U , then it's weight at that point is

The gravitational potential at a point above the surface of earth is -5.12times10^(7)J//kg and the acceleration due to gravity at that point is 6.4m//s^(2) .Assume that the mean radius of earth to be 6400km" .The height of this point above the earth's surface is :

Assertion : If gravitational potential at some point is zero, then gravitational field strength at that point will also be zero. Reason : Except at infinity gravitational potential due to a system of point masses at some finite distance can't be zero.
