Forces Acting on a Swinging Ball: Understanding Tension and Weight

A ball attached to a light string swings in a counterclockwise vertical circle, as shown. Which of the following arrows represent one of the forces exerted on the ball at the moment it passes through point P?

The two forces exerted on the ball at the moment it passes through point P are:

1. Tension force (T) acting upwards along the string, which keeps the ball moving in a circular path.

2. Weight force (W) acting downwards towards the center of the circle, which makes the ball experience a centripetal acceleration.
