A van is moving with a speed of `72Kmph` on a level road, where the coefficient of friction between tyres and road is `0.5`. The minimum radius of curvature, the road must have, for safe driving of van is

`10 m`

`20 m`

`5 m`

`15 m`

Text Solution

Verified by Experts

The correct Answer is:

`(mv^(2))/r=mumg,v=sqrt(mu r g) rArr r=v^(2)/(mu_(s)g)`
