Physics-Young's Modulus
NEET Physics Young's Modulus Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 11
Assertion (A): Young's modulus is a measure of the stiffness of a material. | Reason (R): Young's modulus is defined as the ratio of tensile stress to tensile strain within the elastic limit of a material.
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.
D
A is false but R is true.
Correct Answer
Option A
Detailed Explanation
Young's modulus quantifies stiffness since it relates stress and strain in the elastic region, as stated in the NCERT context.
