    The minimum velocity (in ms-1) with which a car driver must traverse a flat curve of radius 150 m and coefficient of friction to avoid skidding is

    A)  60                                         

    B)  30

    C)   15                                        

    D)  25

    Correct Answer: B

    Solution :

                     Using the relation \[\frac{m{{v}^{2}}}{r}=\mu R,R=mg\] \[\frac{m{{v}^{2}}}{r}=\mu mg\]or \[{{v}^{2}}=\mu rg\] \[{{v}^{2}}=0.6\times 150\times 10\] \[v=30\text{ }m/s\]
