NEET Physics Stress & Strain MCQ Question

Type: MCQ-conceptual-Easy-Class 11

Which of the following statements about stress and strain in solids is correct?

A

Tensile stress is defined as the force applied per unit area, equal to F/A.

B

Hooke’s law is applicable in all regions of the stress-strain curve.

C

Bulk modulus is only relevant for solids and not applicable for liquids or gases.

D

The strain in a material is defined as the ratio of stress to Young's modulus.

Correct Answer

Option A

Detailed Explanation

The definition of tensile stress as the force applied per unit area (F/A) is correct. Hooke’s law is only valid in the linear part of the stress-strain curve, and bulk modulus applies to solids, liquids, and gases. Strain is defined as the ratio of change in length to original length, not related to Young's modulus directly.
