# A \(250 \, \text{newton}\) centripetal force acts on a car 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 car?

A \(250 \, \text{newton}\) centripetal force acts on a car 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 car?

- **A.** \(v\) decreases and \(f\) decreases
- **B.** \(v\) increases and \(f\) decreases
- **C.** \(v\) decreases and \(f\) increases
- **D.** \(v\) increases and \(f\) increases
- **E.** None of the above
