A car moves along a horizontal circular road of radius r with velocity V . The coefficient of friction between the wheels and the road is $\mathrm{\mu }$ . Which of the following statement is not true ? 
 

The car will slip if $\mathrm{\mu }<\frac{{\mathrm{v}}^2}{\mathrm{rg}}$
 

The car will slip if $\mathrm{\mu }>\frac{{\mathrm{v}}^2}{\mathrm{rg}}$
 

The car will slip if $\mathrm{v}>\sqrt{\mathrm{\mu rg}}$
 

The car will slip at lower speed, if it moves with some tangential acceleration, than if it moves at constant speed.
