The density of a metal at normal pressure P is . When it is subjected to an excess pressure, the density becomes ^ . If K is the bulk modulus of the metal, then the ratio ^ is
Options
- A1+ K P
- B1+ P K
- C1 1- K P
- D1 1- P K
Correct answer
D. 1 1- P K
Step-by-step solution
B =- V dP dV Thus, V =- pV B or V ^ - V =- pV B Or , V ^ = V (1- p B ) Now, ^ = m V^ = m V (1- p B ) = (1- p B )
