NEET Physics Stress & Strain Assertion Reason Question
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.
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
Both statements are true. Tensile stress causes elongation and the definition of strain as change in length over original length explains this.
