For traffic moving at 60 km//hour along a circular track of radius 0.1 km, the correct angle of banking is

For traffic moving at 60 km/hour along a circular track of radius 0.1 km, the correct angle of banking is

For traffic moving at 60 km//hour along a circular track of radius 0.1 km, the correct angle of banking is

If a car is to travel with a speed v along the frictionless, banked circular track of radius r , the required angle of banking so that the car does skid is
