A Car moving in circular motion

[interxavier]

Homework Statement

Suppose you are driving a car around in a circle of radius 200 ft, at a velocity which has the constant magnitude of 20 ft/s. A string hangs from the ceiling of the car with a mass of 2 kg suspended from it. What angle will the string make with the vertical? (Away from the center of curvature)

Homework Equations

Fr = mrw^2
v = rw

The Attempt at a Solution

Basically, the part about the string hanging from the ceiling of the car makes this problem confusing. My understanding is that if the car moves in uniform circular motion (constant speed), then the angle of the string will not vary. The thing is, the string will lean towards the center of curvature while the car is moving in a circular path (correct me, if I'm wrong).

let me ask you this:

Which forces are acting on the object suspended from the ceiling of the car?
