NEET Physics Elastic Behavior Assertion Reason Question
Assertion (A): When a force is applied to a solid body, it always returns to its original shape once the force is removed. | Reason (R): The restoring force developed in a body is equal in magnitude but opposite in direction to the applied force.
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 but R is true.
Correct Answer
Detailed Explanation
A is false because not all solid bodies return to their original shape once the deforming force is removed, as permanent deformation can occur. R is true as per the definition of stress.
