The period of circular motion is:
Correct answer: A. T=2π/ω
- A. T=2π/ω
- B. T=2πω
- C. T=ω/2π
- D. T=πω/2
Explanation
The correct answer is option A: T = 2π/ω. The period of circular motion is given by T = 2π/ω, where T represents the period and ω represents the angular velocity. Options B, C, and D are incorrect as they involve incorrect operations on the given formula, leading to incorrect expressions for the period of circular motion.

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.
