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 $\left({ }^{\prime} \mathrm{g}^{\prime}=\right.$ acceleration due to gravity $)$
$\sqrt{\frac{\mu g}{r}}$
$\sqrt{\frac{r \mu}{g}}$
$\sqrt{\frac{g}{r \mu}}$
$\sqrt{\frac{r g}{\mu}}$
Solution
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 \(\sqrt{\frac{r g}{\mu}}\).
