Let TA and TB be the time periods of particle A and B respectively. According to the question, if ωA and ωB are their angular speeds, then:

1. ωA = 2π / TA
2. ωB = 2π / TB
3. ωA / ωB = TB / TA = T / T = 1:1
4. None of these

Correct answer: ωA = 2π / TA

Solution

The angular speed ω is related to the time period T by the formula ω = 2π / T. Thus, ωA = 2π / TA is correct.
