Young's modulus for perfectly rigid body is
- A zero
- B infinite
- C \(1 \times 10^{10} \mathrm{Nm}^{-2}\)
- D \(10 \times 10^{10} \mathrm{Nm}^{-2}\)
Answer & Solution
Correct Answer
(B) infinite
Step-by-step Solution
Detailed explanation
In perfectly rigid body, there is no change in its dimensions on applying a deforming force, therefore strain in the perfectly rigid body is zero. \(\therefore\) Young's modulus \(=\frac{\text { Stress }}{\text { Strain }}=\frac{\text { Stress }}{0}=\infty\) Therefore, Young's…
