Q138 / 180 · AIIMS 2015 · Physics

For a constant hydraulic stress $P$ on an object with bulk modulus $(B)$, the fractional change in the volume of object will be

  • Correct answer
    A
    $\frac{P}{B}$
  • B
    $\frac{B}{P}$
  • C
    $\sqrt{\frac{P}{B}}$
  • D
    $\left(\frac{B}{P}\right)^2$

Solution

Bulk modulus, $B=\frac{-\Delta P}{\Delta V / V}$ or $\left|\frac{\Delta V}{V}\right|=\frac{P}{B}$

Hence, the correct answer is option: 'A'.
