Two identical heavy spheres are separated by a distance 10 times their radius. Will an object placed at the mid-point of the line joining their centres be in stable equilibrium or unstable equilibrium ? Give reason for your answer.

Two identical heavy sphers are separated by a distance 10 times their radius. Will an object planed at the mid point of the line joining their centres be in stable equilibrium or unstable equilibrium ? Give reason for your answer.

Two identical heavy spheres are separated by a distance 10 times their radius. Will an object placed at the mid point of the line joining their centres be in stable equillibrium or unstabel equilibrium ? Give reason for your answer.
