    Find the maximum velocity for skidding for a car moved on a circular track of radius 100 m. The coefficient of friction between the road and tyre is 0.2 [CPMT 1996; Pb. PMT 2001]

    A)             0.14 m/s

    B)                      140 m/s

    C)             1.4 km/s

    D)                      14 m/s

    Correct Answer: D

    Solution :

                    \[{{v}_{\max }}=\sqrt{\mu rg}=\sqrt{0.2\times 100\times 9.8}=14m/s\]
