Gravitational potential at a distance 'r' from a point mass 'm' is V = -(GM)/(r) Find gravitational field strength at that point.

The gravitational potential at a point due to a point mass is V=

Show that the gravitational potential at a point, distance r from the mass M is given by V =-(GM/r)

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.
