    If B is the bulk modulus of a metal and a pressure p is applied uniformly on all sides of the metal with density D, then the fractional increase in density is given by

    A)  \[\frac{B}{p}\]                                 

    B)  \[\frac{p}{B}\]

    C)  \[\frac{pD}{B}\]                                              

    D)  \[\frac{BD}{p}\]

    Correct Answer: B

    Solution :

       \[{{h}_{A}}<{{h}_{B}}\]   \[{{d}_{A}}>{{d}_{B}}\] \[{{c}_{2}}\] \[{{c}_{2}}\] and we know that \[{{c}_{1}}\] \[={{E}_{i}}\]      \[={{E}_{f}}\] Or Fractional increase in density \[{{E}_{i}}=\frac{-GMm}{R}:\]
