    A road is 10 m wide. Its radius of curvature is 50 m. The outer edge is above the lower edge by a distance of 1.5 m. This road is most suited for the velocity

    A)             2.5 m/sec

    B)                      4.5 m/sec

    C)             6.5 m/sec

    D)                      8.5 m/sec

    Correct Answer: D

    Solution :

                    \[\frac{{{v}^{2}}}{rg}=\frac{h}{l}\]Þ\[v=\sqrt{\frac{rgh}{l}}\]\[=\sqrt{\frac{50\times 1.5\times 9.8}{10}}=8.57\,m/s\]
