When a car goes around a banked circular curve at the proper speed for the banking angle,what force cause it to follow the circular path?
A)the normal force exerted by the road on the car perpendicular to the road's surface
B)the friction force exerted by the road on the car
C)the force that Earth exerts on the car
D)No force causes the car to do this because the car is traveling at constant speed and therefore has no acceleration.

The normal force exerted by the road on the car perpendicular to the road's surface is the force that causes the car to follow the circular path. This force acts as the centripetal force required for circular motion. The friction force and the force exerted by the Earth on the car are not responsible for causing the car to follow the circular path, as they act in different directions. The option D is incorrect since a car moving in a circular path has acceleration, as its direction of motion is constantly changing.
