$Young's modulus of a perfect rigid body is$

Topic: JEE PYQ

Answer: A. Full step-by-step solution below.

A $infinity$
B $between zero and unity$
C $zero$
D $unity.$

Correct answer: A

Solution

(a): Young's modulus, Y = \frac{stress}{strain} For a perfectly rigid body, strain = 0 ∴ Young's modulus is infinite.
