NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 11
Assertion (A): For small deformations, stress is directly proportional to strain in many materials. | Reason (R): Young's modulus is the constant of proportionality between stress and strain for tensile stress.
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
The NCERT context states that for small deformations, stress is proportional to strain, which is Hooke's law. Young's modulus is the constant of proportionality for tensile stress, explaining the assertion.
