A 0.21 kg ball on a string is whirled on a vertical circle at a constant speed. When the ball is at the three o'clock position, the tension is 18 N.

(c) Is the tension in the string greater when the ball is at the twelve o'clock position or when it is at the six o'clock position, or is the tension the same at both positions?

The tension is the same at both positions.

The tension is greater at the six o'clock position.

The tension is greater at the twelve o'clock position.
