Question

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 'µ', the minimum speed of motorcyclist to prevent him from skidding is ______.

('g' =acceleration due to gravity)

Options

• `sqrt((rmu)/g)`

• `sqrt((mug)/r)`

• `sqrt((rg)/mu)`

• `sqrt(g/(rmu))`

Answer 1

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 'µ', the minimum speed of motorcyclist to prevent him from skidding is `underline(sqrt((rg)/mu))`.
