24. A centripetal force of 5.0 newtons is applied to a rubber stopper moving at a constant speed in a horizontal circle. If the same force is applied, but the radius is made smaller, what happens to the speed, v, and the frequency, f, of the stopper?
(A) v increases and f increases
(B) v decreases and f decreases
(C) v increases and f decreases
(D) v decreases and f increases
