    Joule second is the unit of

    A)  momentum                      

    B)  angular momentum

    C)  work

    D)  pressure

    Correct Answer: B

    Solution :

                     Angular momentum of a body about an axis of rotation is given by                 \[J=I\omega \] where I is moment of inertia, co the angular velocity. The SI unit of angular momentum is \[kg\,{{m}^{2}}{{s}^{-1}}\]or Joule-second. While momentum p = mv has unit kg \[m{{s}^{-1}}\], work has unit of Joule and pressure has unit dyne.
