NEET Physics Stress & Strain Assertion Reason Question
Assertion (A): The Young's modulus of a material is a measure of its ability to withstand changes in length under tensile stress.
Reason (R): The Young's modulus is the ratio of tensile stress to the corresponding tensile strain.
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
Both the assertion and the reason are true, and the reason correctly explains the assertion. Young's modulus is defined as the ratio of tensile stress to tensile strain, reflecting a material's ability to resist length changes under stress.
