Assertion: If a spring is stretched from one side, the size and shape of the spring changes.
Reason: Unbalanced force acting on the spring changes the size and shape of the spring in the direction of application.

Explanation:
When a spring is stretched or compressed, its size and shape change. This change in size and shape is due to the unbalanced force acting on the spring.

Assertion (A) is true because when a spring is stretched, it becomes longer and thinner, and when it is compressed, it becomes shorter and thicker. This change in size and shape is easily observable in real life.

Reason (R) is true because the change in size and shape of the spring is caused by the unbalanced force acting on it. When a force is applied to stretch or compress the spring, the atoms or molecules in the spring are displaced from their equilibrium positions. This displacement leads to a change in interatomic or intermolecular forces, causing the spring to change its size and shape.

Reason (R) is the correct explanation of assertion (A) because the unbalanced force acting on the spring is the underlying cause of the change in size and shape. Without the force, the spring would remain in its original size and shape.

To summarize, when a spring is stretched or compressed, its size and shape change due to the unbalanced force acting on it. This change in size and shape can be observed in real life and is explained by the displacement of atoms or molecules in the spring. Thus, both the assertion and reason are true, and the reason is the correct explanation of the assertion.
