Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The property of body, by virtue of which it tends to regain its original shape when the external force is removed, is Elasticity. Reason (R): The restoring force depends upon the bonded inter atomic and inter molecular force of solid. In the light of the above statements, choose the correct answer form the options given below.

1. Both (A) and (R) are true and (R) is the correct explanation of (A)
2. (A) is false but (R) is true
3. (A) is true but (R) is false
4. Both (A) and (R) are true but (R) is not the correct explanation of (A)

Correct answer: Both (A) and (R) are true and (R) is the correct explanation of (A)

Solution

Both statements accurately describe the concept of elasticity; the assertion defines elasticity correctly, while the reason explains that the restoring force, which allows a material to return to its original shape, is indeed related to the interatomic and intermolecular forces within the solid.
