If a body floating in a liquid returns back to its original position, ...
Stable Equilibrium:
When a body floating in a liquid returns back to its original position after being given a small angular displacement, it is said to be in stable equilibrium.

Explanation:
Stable equilibrium refers to a state where a system, in this case, a body floating in a liquid, tends to return to its original position after being disturbed. This occurs when the body's equilibrium is restored and the forces acting on it oppose the displacement.

When a floating body is in stable equilibrium, it means that if it is given a small angular displacement, it will experience a restoring torque that brings it back to its original position. This restoring torque is caused by the difference in the buoyant force acting on different parts of the body.

Key Points:
- Stable equilibrium is characterized by the body's ability to return to its original position after a small angular displacement.
- The restoring torque is generated by the difference in buoyant force acting on different parts of the floating body.
- This equilibrium state is stable because the forces acting on the body oppose the displacement and restore the body to its original position.

Example:
An example of stable equilibrium can be observed when a small toy boat is floating on the surface of water. If the boat is slightly tilted or disturbed, it will naturally tend to return to its original position due to the restoring torque caused by the buoyant force acting on different parts of the boat.

Conclusion:
In conclusion, when a floating body returns back to its original position after being given a small angular displacement, it is said to be in stable equilibrium. This equilibrium state is stable because the forces acting on the body oppose the displacement and restore the body to its original position.
