Ok, I goofed; electrostatic and gravitational forces (in a system
of two point-like positively charged objects), alone, could not
produce a potential minimum. Thanks JohnD.

What evidence do we have to argue that the gravitational 1/r^2
law would be applicable, for example, to two tiny black holes
ready to swallow each other?

In my opinion the answer is NO. If the 1/r^2 laws are valid then
the magnitude of the net electric force is equal to the magnitude
of the net gravitational force at any distance, even when the
point-like particle is in the center of the ring (0=0).
