Question

gravitational potential is maximum at r=​

Answer 1

Answer

As, U=−Grm1m2, 

it can be used to describe the potential energy in a system of point charges (or radially symmetric spheres) as a function of their separation distance r, then the maximum value is zero at infinite separation.

Hence, its maximum value is zero at infinity.

Answer 2

Answer:

its maximum value zero at infinity
