NEET Physics Stress & Strain Assertion Reason Question
Assertion (A): Young's modulus is a measure of the ability of a material to withstand changes in length when under lengthwise tension or compression. | Reason (R): A material with a high Young's modulus requires a large force to produce a small change in 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
Young's modulus quantifies the relationship between stress and strain, as shown by the requirement of large forces for small deformations in materials with high modulus values, like steel, in the NCERT context.
