NEET Physics Elastic Behavior Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 11

Assertion (A): Hooke's Law is applicable for all materials under small deformations.

Reason (R): The modulus of elasticity is the constant of proportionality between stress and strain in Hooke's Law.

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 D

Detailed Explanation

Hooke's Law is not applicable to all materials under small deformations; elastomers do not obey Hooke's Law. However, the modulus of elasticity is indeed the constant of proportionality in Hooke's Law.
