1.	Coefficient of friction between the tyer and the wet road is: a) 0.2 b)0.6 c)0.8 d)1
Answer» Let V be the MAXIMUM speed of the car which is moving around a CURVE of RADIUS 40 m and it is moving with this velocity without SLIPPING. So, frictional force = centripetal forceμmg= Rmv 2 v 2 =μgR v 2 =0.5×40×9.8 v 2 =196m/s v=14m/s μ is coefficient of friction between car and tyre.R is the radius of curvev is the velocity of a car
