Q. 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 $ )

Solution:

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