    The unit of the coefficient of viscosity in S.I. system is

    A) m/kg-s

    B)  \[m-s/k{{g}^{2}}\]

    C)  \[kg/m-{{s}^{2}}\]

    D)  kg/m-s

    Correct Answer: D

    Solution :

    [d] \[F=6\pi \eta vr\Rightarrow \eta =F/6\pi vr\] \[\therefore \] Unit of coefficient of viscosity in S.I. system \[kg/m-s.\]
