    An unbanked curve has a radius of \[60\,m\]. The maximum speed at which a car can make a turn if the coefficient of static friction is 0.75, is                                                                                            [JIPMER 1999]

    A)             2.1 \[m/s\]

    B)                      14 \[m/s\]

    C)             21 \[m/s\]

    D)                      7 \[m/s\]

    Correct Answer: C

    Solution :

                    \[{{v}_{\max }}=\sqrt{\mu rg}=\sqrt{0.75\times 60\times 9.8}=21\,m/s\]
