Step-by-step Solution
Detailed explanation
A motorcyclist rides in a horizontal circle about central vertical axis inside a cylindrical chamber of radius ' \(r\) '. If the coefficient of friction between the tyres and the inner surface of chamber is ' \(\mu\) ', the minimum speed of motorcyclist to prevent him from skidding is \(\sqrt{\frac{r g}{\mu}}\).
