STABLE EQUILIBRIUM

A body is in the position of stable equilibrium if on slight displacement it tends to return to its original position. For example an object with large base and low centre of gravity is usually stable . A cone  resting on its base has a low centre of gravity.

The necessary condition for stable object is that the centre of gravity is at its lowest position

Unstable equilibrium

A body is said to be in position of unstable equilibrium when it receive a slight displacement it tends to move on farther away from its original position.

A body with small base and high centre of gravity is usually unstable.
