    When a motor cyclist moves in a circular track of radius 100 m , then the maximum velocity with which the cyclist can take the turn with leaning inwards is (Take coefficient of friction\[=0.2\,T\])

    A)  \[1.4\,m{{s}^{-1}}\]                       

    B)  \[14\,m{{s}^{-1}}\]

    C)  \[140\,m{{s}^{-1}}\]                      

    D)  \[280\,m{{s}^{-1}}\]

    Correct Answer: B

    Solution :

                    Maximum velocity, \[v=\sqrt{\mu rg}\] \[=\sqrt{0.2\times 100\times 10}\] \[=10\sqrt{2}=14\,m{{s}^{-1}}\]
