NEET Physics Stress & Strain MCQ Question
Which of the following statements about stress and strain in solids is correct?
Tensile stress is defined as the force applied per unit area, equal to F/A.
Hooke’s law is applicable in all regions of the stress-strain curve.
Bulk modulus is only relevant for solids and not applicable for liquids or gases.
The strain in a material is defined as the ratio of stress to Young's modulus.
Correct Answer
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.
