A ball balanced on a vertical rod is an example of
- stable equilibrium
- unstable equilibrium
- neutral equilibrium
- perfect equilibrium
Answer
There are three states of equilibrium: stable, unstable and neutral.
Stable equilibrium is when the center of gravity of a body lies below point of suspension or support. For example a book lying on a table is in stable equilibrium.
Unstable equilibrium is when the center of gravity of a body lies above the point of suspension or support.
Neutral equilibrium is when the center of gravity of a body lies at the point of suspension or support. Example: rolling ball.
The correct option is B.
