Question
What is Bulk modulus for a perfectly rigid body?
✓
Answer
Bulk modulus $(\text{B})=\frac{\rho}{\frac{\Delta\text{V}}{\text{V}}}=\frac{\rho\text{V}}{\Delta\text{V}}$ For perfectly rigid body, change iin volume $\Delta\text{V}=0$ $\therefore\text{B}=\frac{\rho\text{V}}{0}=\infty$ Therefore, Bulk modulus for a perfectly rigid body is $\infty.$
