Modulus of rigidity of a liquid
Correct answer: D. Cannot be predicted
- A. Non zero constant
- B. Infinite
- C. Zero
- D. Cannot be predicted
Explanation
The modulus of rigidity, also known as shear modulus, is a property that measures a material's ability to withstand shear stress. It is applicable to solids, where deformation under shear stress can be measured. However, liquids cannot sustain shear stress; they flow instead of deforming elastically. Therefore, the concept of modulus of rigidity does not apply to liquids, and it cannot be predicted. Options A, B, and C are incorrect because they attempt to apply a concept to a state of matter where it does not hold.
