Physics-Young's Modulus
NEET Physics Young's Modulus MCQ Question
Type: MCQ-conceptual-Hard-Class 11
Which of the following statements about Young's Modulus is correct?
A
Young's Modulus is defined as the ratio of stress to strain in the elastic region.
B
Young's Modulus can be exceeded without causing permanent deformation.
C
Higher Young's Modulus values indicate that a material is more ductile.
D
Young's Modulus has no relationship with the yield strength of a material.
Correct Answer
Option A
Detailed Explanation
Young's Modulus is indeed defined as the ratio of stress to strain in the elastic region, which helps determine how much a material will deform under stress. Options B, C, and D reflect misconceptions about the behavior of materials under stress and their physical properties.
