NEET Physics Stress & Strain MCQ Question
Which of the following statements regarding stress and strain is correct?
Stress is the restoring force per unit area while strain is the total change in dimension.
Strain has units and stress does not, as stress is a dimensionless quantity.
Young's modulus is a measure of the ratio of stress to strain in the elastic region.
All solids exhibit the same Young's modulus regardless of material type.
Correct Answer
Detailed Explanation
Young's modulus is defined as the ratio of stress to strain for small deformations, indicating the elasticity of a material. This is consistent with the principles outlined in the NCERT context regarding stress and strain.
