Young's modulus for perfectly rigid body is

Options

  1. Azero
  2. Binfinite
  3. C1 10¹⁰ Nm ⁻²
  4. D10 10¹⁰ Nm ⁻²

Correct answer

B. infinite

Step-by-step solution

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. Young's modulus = Stress Strain = Stress 0 = Therefore, Young's modulus of a perfectly rigid body is infinite.
