    A car of mass 1000 kg moves on a circular track of radius 20 m. If the coefficient of friction is 0.64, then the maximum velocity with which the car can move is:

    A)  15 m/s                                

    B)  11.2 m/s

    C)  20 m/s                

    D)         18 m/s

    E)  22.4 m/s

    Correct Answer: B

    Solution :

    The relation between centripetal force and frictional force is \[F=\mu mg=\frac{m{{v}^{2}}}{r}\] \[v=\sqrt{\mu gr}=\sqrt{0.67\times 9.8\times 20}\] \[=11.2m/s\]
