# A car of mass \(m\) is traveling at a constant speed \(v\) around a vertical circular track of radius \(R\). The car successfully maintains contact with the track throughout the motion. Which of the following diagrams best represents the individual forces exerted on the car and the direction of the net force \(\vec{F}_{net}\) at the instant the car is at the highest point of the loop?

![A side view of a circular track (a loop-the-loop). A small car is located at the 12 o'clock position (the very top of the circle), on the inside of the track. An arrow indicates the car is moving to the left with speed v. The center of the circle is marked with a point.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1775869202-4yWjQZ.jpg)
