The correct Answer is:
To determine the modulus of rigidity of a liquid, we need to understand the relevant concepts in elasticity. The modulus of rigidity, also known as shear modulus, is a measure of a material's ability to resist shear deformation. However, liquids do not have a shear modulus in the same way that solids do because they cannot maintain a shape under shear stress. Instead, we refer to the bulk modulus for liquids. ### Step-by-Step Solution: 1. **Understand the Terms**: - **Modulus of Rigidity (Shear Modulus)**: This is defined for solids and measures the material's response to shear stress. - **Bulk Modulus**: This is defined for liquids and measures the material's response to uniform pressure applied in all directions. 2. **Identify the Modulus for Liquids**: - For liquids, the relevant modulus is the bulk modulus (denoted as \( K \)). The bulk modulus quantifies how incompressible a liquid is when pressure is applied. 3. **Conclusion**: - Since the question asks about the modulus of rigidity of a liquid, the correct answer is that it is represented by the bulk modulus. Therefore, the modulus of rigidity of a liquid is effectively the bulk modulus. ### Final Answer: The modulus of rigidity of a liquid is the bulk modulus. ---
