. Modulus of rigidity of ideal liquids is
A: infinity
B: zero
C: unity
D: some finite small non - zero constant value
Best Answer
Explanation:
- Modulus of rigidity is also called shearing modulus. It is defined as,
η= Shearing Stress /Shearing Strain
- Since ideal liquid cannot sustain shearing stress, therefore
η=0
Final answer:
Hence the correct option is (B), i.e. zero
