Question

The figure shows a dish kept at an orientation with a marble placed on it. If the marble in figure is displaced slightly, it would rattle about for a while and come to rest in its original place. This is an example of :

• A. unstable equilibrium
• B. Stable Equilibrium
• C. Metastable equilibrium
• D. Centre of gravity principle

Answer 1

The correct option is B

Stable Equilibrium

If a dish is kept at an orientation with a marble placed on it and if the marble in figure is displaced slightly, it would rattle about for a while and come to rest in its original place. This is the example of Stable Equilibrium.

When a body tries to regain its equilibrium position after being slightly displaced and released, it is said to be in stable equilibrium.
