Answer:
The centripetal force is provided by the x component of the Normal Force.
Explanation:
The centripetal force is a force that makes something to follow a cicular trayectory, this force is always oriented to the center of the circunferency-
So you can see in the image that i attached there is only two forces actting on the car, the normal force and the weigth, and as you can see the y component of the normal force cancels with the weigth, but the x component of the normal force (as it has nothing to cancel with) makes the car follow the circular trayectory so this is the centripetal force.
