    The maximum tension which an in extensible ring of mass 0.1 kg/m can bear is 10 N. The maximum velocity in m/s with which it can be rotated is

    A)  10                                         

    B) \[\sqrt{10}\]

    C)  20                                         

    D)  15

    Correct Answer: A

    Solution :

                    From the relation, \[T=\mu {{r}^{2}}{{\omega }^{2}}=\mu {{v}^{2}}\]            (\[\because \]\[v=r\omega \]) \[{{v}^{2}}=\frac{T}{\mu }\] \[v=\sqrt{\frac{T}{\mu }}\]                 \[\therefore \]  \[v=\sqrt{\frac{10}{0.1}}\]                                 \[v=\sqrt{100}=10m/s\]
