a. Unstable Equilibrium b. Stable Equilibrium c. Neutral Equilibrium Unstable Equilibrium: When given a small angular displacement if the body does not return to its original position from the slightly displace original position and heels further away, these types of equilibrium is called unstable equilibrium. Stable Equilibrium: By providing some external force and then it’s return back to its original position due to internal forces such as the upthrust and the weight, when a body is given a small angular displacement. This types of equilibrium is called stable equilibrium. Neutral Equilibrium: If a body occupies a new position and remains at rest in this new position , when given a small angular displacement.
