MCQ
Modulus of rigidity of ideal liquids is
  • A
    Infinity.
  • ✓
    Zero.
  • C
    Unity.
  • D
    Some finite small non - zero constant value.
✓

Answer

Correct option: B.
Zero.
As the liquid is ideal, hence it does not have frictional force among it's layers, thus the tangential forces are zero as there is no stress developed. This verifies.
