Answer:

The gravitational field at the mid-point of the line joining the centers of the two spheres =

(r/2)

Gravitational potential at the midpoint of the line joining the centres of the two spheres is V=−

J/kg

As the effective force on the body placed at mid-point is zero, so the body is in equilibrium. If the body is displaced a little towards either mass body from its equilibrium position, it will not return back to its initial position of equilibrium. Hence, the body is in an unstable equilibrium
