    A van is moving with a speed of 72 km/h on a level road. Where the coefficient of friction between its tyres and road is 0.5. The minimum radius of curvature, that the road must have, for safe driving of van is\[(g=10m{{s}^{-2}})\]:

    A)  80 m                                    

    B)  40 m

    C)  20 m                                    

    D)  4 m

    Correct Answer: A

    Solution :

                     From the relation, \[\mu mg=\frac{m{{v}^{2}}}{r}\] \[\Rightarrow \]               \[r=\frac{{{v}^{2}}}{\mu g}\]  (Given:\[v=72\,km/h=72\times \frac{5}{18}=20\,m/s,\]                \[\mu =0.5,g=10\,m/{{s}^{2}}\]) \[=\frac{{{(20)}^{2}}}{0.5\times 10}=\frac{400}{5}=80m\]
