    A spherical ball contracts in volume by 0.02% when subjected to a pressure of 100 atmosphere. Assuming one atmosphere \[={{10}^{5}}N{{m}^{-2}}\], the bulk modulus of the material of the ball is

    A) \[0.02\times {{10}^{5}}N/{{m}^{2}}\]

    B) \[0.02\times {{10}^{7}}N/{{m}^{2}}\]

    C) \[50\times {{10}^{7}}N/{{m}^{2}}\]

    D) \[50\times {{10}^{9}}N/{{m}^{2}}\]

    Correct Answer: D

    Solution :

    [d] \[B=-\frac{\Delta P}{\Delta V/V}=\frac{100\times {{10}^{5}}}{(0.02/100)}\] \[=50\times {{10}^{9}}N/{{m}^{2}}s\]
