    For a constant hydraulic stress on an object, the fractional change in the objects volume (\[{{K}_{f}}=500-25=475J\]) and its bulk modulus (B) 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)       \[\frac{\Delta V}{V}\propto {{B}^{-2}}\]

    Correct Answer: B

    Solution :

                    When strain is small the ratio of the normal stress to the volume strain is called the bulk modulus of the material of the body. \[{{\mu }_{e}}>{{\mu }_{h}}\] \[{{\mu }_{e}}<{{\mu }_{h}}\] \[{{\mu }_{e}}={{\mu }_{h}}\] \[{{\mu }_{e}}<0;{{\mu }_{h}}>0\]   \[(\mu )\]
