Q99 / 120 · VITEEE 2019 · Physics

The Young's modulus of a perfectly rigid body is

  • A
    unity
  • B
    zero
  • Correct answer
    C
    infinity
  • D
    some finite non-zero constant

Solution

For a perfectly rigid body strain produced is zero for the given force applied, so $Y=$ stress $/$ strain $=$ Infinite $(\infty)$

Hence, the correct answer is option: 'C'.
