Answer:
The top of the circle
Explanation:
At the top of the circle, there are two forces pulling the ball towards the center of the circle: weight and tension.
∑F = ma
mg + T = mv²/r
As v goes down, T also goes down, until it eventually reaches 0.
At the bottom of the circle, weight is pulling down, or away from the center of the circle. Sum of the forces:
∑F = ma
T − mg = mv²/r
As v goes down, T also goes down. However, even at v=0, T cannot be less than mg.
