    The maximum velocity \[\left( inm{{s}^{1}} \right)\] with which a car driver must traverse a flat curve of radius 150 m and coefficient of friction 0.6 to avoid skidding is                      [AIEEE 2002]

    A)             60       

    B)             30

    C)             15       

    D)             25

    Correct Answer: B

    Solution :

                    \[v=\sqrt{\mu rg}=\sqrt{0.6\times 150\times 10}=30\,m/s\]
