The maximum speed that can be achieved without skidding by a car on a circular unbanked road of radius $R$ and coefficient of static friction $\mu $, is
The maximum speed that can be achieved without skidding by a car on a circular unbanked road of radius $R$ and coefficient of static friction $\mu $, is
$\mu Rg$
$Rg\sqrt \mu $
$\mu \sqrt {Rg} $
$\sqrt {\mu Rg} $
The maximum speed that can be achieved without skidding by a car on a circular unbanked road of radius $R$ and coefficient of static friction $\mu $, is
In the given condition the required centripetal force is provided by frictional force between the road and tyre.
$\frac{{m{v^2}}}{R} = \mu \,mg$
$\therefore v = \sqrt {\mu \;Rg} $
