Ex. 64: A car can be driven on a flat circular road of radius r at a maximum speed v without skidding. The same car is now driven on another flat circular road of radius 2r on which the coefficient of friction between the tyres and the road is the same as on the first road. What is the maximum speed of the car on the second road such that it does not skid ?
