A car of mass m goes around a banked curve of radius r with speed v. If the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to A)mg/2. B)mg. C)mg sinθ . D)mv²/r. E)tan[v²/(rg)].

Question

The horizontal component of the normal force provides the necessary centripetal force for the car to negotiate the curve. This force is equal to mv²/r, which is the centripetal force required for circular motion.
