    For a constant hydraulic stress on an object, the fractional change in the objects volume \[\left( \frac{\Delta V}{V} \right)\]and its bulk modulus  are related as

    A)  \[\frac{\Delta V}{V}\propto B\]                               

    B)  \[\frac{\Delta V}{V}\propto \frac{1}{B}\]

    C)  \[\frac{\Delta V}{V}\propto {{B}^{2}}\]                                

    D)  \[\frac{\Delta V}{V}\propto {{B}^{-2}}\]

    E)  \[\frac{\Delta V}{V}\propto {{B}^{3/2}}\]

    Correct Answer: B

    Solution :

                    \[B=\frac{p}{\frac{\Delta V}{V}}\] If p is constant, then \[\frac{\Delta V}{V}\propto \frac{1}{B}\]
