NEET Physics Elastic Behavior Assertion Reason Question
Assertion (A): The deformation of a solid body under a small applied force is elastic. | Reason (R): In solids, the tight coupling between neighboring atoms causes them to return to their original positions once the force is removed.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
The assertion is true because elastic behavior is observed when deformation is reversible. The reason explains that the tight coupling between atoms in solids is responsible for their ability to revert to the original shape.
