    A point on the rim of a wheel 400 cm in diameter has a velocity of 1600 cm/s. The angular velocity of the wheel is:

    A)  6 rad/s                                

    B)  4 rad/s

    C)  2 rad/s                                

    D)  8 rad/s

    Correct Answer: D

    Solution :

     The relation between angular velocity and linear velocity is given \[v=r\omega \] (where r is the radius of wheel, \[\omega \] is angular speed of wheel) \[v=1600\text{ }cm/s\]                  \[D=400\,cm\] \[r=\frac{D}{2}=200\,cm\] \[\omega =\frac{v}{r}\] \[=\frac{1600\times {{10}^{-2}}}{200\times {{10}^{-2}}}\] \[=8\,rad/s\]
