The ratio of angular frequency and linear frequency is:
Correct answer: A. 2π
- A. 2π
- B. π
- C. 1/2π
- D. π/2
Explanation
Angular frequency ω relates to ordinary frequency f by ω = 2πf, so the ratio ω/f = 2π. Thus option A is correct.

About Angular Velocity
Angular velocity describes how quickly angular displacement changes with time, with ω = Δθ/Δt and units of radians per second. Questions relate angular and linear motion through v = rω, use the direction given by the right hand rule, and distinguish angular velocity from angular acceleration and ordinary frequency.
