    A mass M is supported by a massless string wound round a uniform cylinder of mass M and radius R as shown. The mass is released from rest. The acceleration with which it falls down is

    A)       \[\frac{g}{3}\]                                               

    B)  \[\frac{g}{2}\]

    C)                  \[\frac{2g}{3}\]               

    D)  \[\frac{3g}{3}\]

    Correct Answer: C

    Solution :

                        \[a=\frac{g}{1+\frac{\frac{1}{2}M{{R}^{2}}}{M{{R}^{2}}}}=\frac{g}{\frac{3}{2}}=\frac{2g}{3}.\]
