    A homogeneous solid cylindrical roller of radius R and mass M is pulled on a cricket pitch by a horizontal force. Assuming rolling without slipping, angular acceleration of the cylinder is:

    A) \[\frac{3F}{2mR}\]

    B) \[\frac{F}{3mR}\]

    C) \[\frac{F}{2mR}\]

    D) \[\frac{2F}{3mR}\]

    Correct Answer: D

    Solution :

    \[F-f=ma\]
    \[fR=\frac{1}{2}m{{R}^{2}}\alpha \]
    \[a=\alpha R.\]
