NEET Physics Stress & Strain Assertion Reason Question

Type: Assertion Reason-assertion-Easy-Class 11

Assertion (A): A solid body under tensile stress elongates by ∆L. | Reason (R): The strain in a solid body is the ratio of change in length to the original length.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.
