The density and bulk modulus of a metal bar is ' e ' and ' K ' respectively. When pressure 'P' is applied from all sides to that metal bar, the increase in its density is
Options
- AQ P (K+P)
- BQ P (K-P)
- CK-P Q
- DK + P Q
Correct answer
B. Q P (K-P)
Step-by-step solution
= M / V d =- dV V k =- P dV V - dV V = P k d = P k d = P k
