A race-car driver is driving in a circle at a fixed velocity. He has a cross hanging down from a string on his rearview mirror. Which of the listed forces impacts the hanging cross as the driver drives around a circle at a fixed velocity?

Gravity, Friction, Tension, and Centripetal Force

I say gravity, tension, and centripetal force.

Is this correct?

as it is steady state you are correct as long as you can disregard the static friction within the strands of the string?
