# A car with speed \( v \) and an identical car with speed \( 3v \) both travel the same circular section of an unbanked road. If the frictional force required to keep the faster car on the road without skidding is \( F \), then the frictional force required to keep the slower car on the road without skidding is

A car with speed \( v \) and an identical car with speed \( 3v \) both travel the same circular section of an unbanked (flat) road. If the frictional force required to keep the faster car on the road without skidding is \( F \), then the frictional force required to keep the slower car on the road without skidding is

- **A.** \( 9F \)
- **B.** \( 4.5F \)
- **C.** \( F \)
- **D.** \( \frac{2F}{9} \)
- **E.** \( \frac{F}{9} \)
