    Bulk modulus of water is\[2\,\,\times \,\,{{10}^{9}}\,Nm{{\,}^{-}}^{2}\]. The change in pressure required to increase the density of water by \[0.1\,\,%\] is

    A) \[2\,\,\times \,\,{{10}^{9}}\,N{{m}^{-}}^{2}\]           

    B) \[2\,\,\times \,\,{{10}^{8}}\,N{{m}^{-}}^{2}\]

    C) \[2\,\,\times \,\,{{10}^{6}}\,N{{m}^{-}}^{2}\]           

    D) \[2\,\,\times \,\,{{10}^{4}}\,N{{m}^{-}}^{2}\]

    Correct Answer: C

    Solution :

    The density would increase by 0.1 % if the volume decrease by 0.1 % \[K=\frac{\Delta P}{\frac{\Delta V}{V}}\] \[=\,\,\,2\times {{10}^{9}}\times \frac{0.1}{100}\] \[=\,\,2\,\,x\,\,{{10}^{6}}\,N{{m}^{-2}}\]
