# Two object rests on a platform rotating at constant speed. Object A is at distance of half the platform’s radius from the center. Object B lays at edge of the platform. Assuming the platform continues rotating at the same speed, how does the centripetal force of the two objects compare? 

Two identical object rests on a platform rotating at constant speed. Object A is at distance of half the platform’s radius from the center. Object B lays at edge of the platform. Assuming the platform continues rotating at the same speed, how does the centripetal force of the two objects compare?

- **A.** \[ F_A = 4F_B \]
- **B.** \[ F_A = 2F_B \]
- **C.** \[ F_A = F_B \]
- **D.** \[ F_A = \frac{1}{2} F_B \]
- **E.** \[ F_A = \frac{1}{4}F_B \]
