Two heavy spheres each of mass 100 kg and radius 0.10 m are placed 1.0 m apart on a horizontal table. What is the gravitational force and potential at the mid point of the line joining the centres of the spheres ? Isan object placed at that point in equilibrium? If so, is the equilibrium stable or unstable ?

1.	Two heavy spheres each of mass 100 kg and radius 0.10 m are placed 1.0 m apart on a horizontal table. What is the gravitational force and potential at the mid point of the line joining the centres of the spheres ? Isan object placed at that point in equilibrium? If so, is the equilibrium stable or unstable ?
Answer» Solution :0.27`xx10^(8)` J/kg, an OBJECT PLACED at the mid point is in an unstable EQUILIBRIUM
