    If a cyclist moving with a speed of 4.9 m/s on a level road can take a sharp circular turn of radius 4 m, then coefficient of friction between the cycle tyres and road is [AIIMS 1999; AFMC 2001]

    A)             0.41    

    B)             0.51

    C)             0.61

    D)             0.71

    Correct Answer: C

    Solution :

                    \[\mu =\frac{{{v}^{2}}}{rg}=\frac{{{(4.9)}^{2}}}{4\times 9.8}=0.61\]
