    A block connected to a spring oscillates vertically. A damping force\[{{F}_{d}}\] , acts on the block by the surrounding medium. Given as \[{{F}_{d}}=-bVb\] is a positive constant which depends on :

    A) viscosity of the medium

    B) size of the block

    C) shape of the block

    D) All of these

    Correct Answer: D

    Solution :

    [d] \[F=-bV\], b depends on all the three i.e. shape and size of he block and viscosity of the medium.
