# A car moves at a speed of $36 \;km\;h^{-1}$ on a level road, The coefficient of fraction between the tyres and the road is $0.8$. The car negotiates a curve of radius R. If $g =10 ms^2$ the car will skid (or slip) while negotiating the curve if value of R is
$\begin{array}{1 1} 10\; m \\ 13\;m \\ 14\;m \\ 16 \;m \end{array}$
