Modulus of rigidity of an incompressible liquid is
- A Non zero constant
- B Zero
- C Cannot predict
- D Infinite
Answer & Solution
Correct Answer
(B) Zero
Step-by-step Solution
Detailed explanation
The modulus of rigidity, also known as the shear modulus (\(G\)), is defined as the ratio of shear stress to shear strain. For a fluid, shear stress is proportional to the rate of shear strain, not the shear strain itself. When a static shear force is applied to a liquid, it…
