A particle revolving in a circular path travels the first half of the circumference in 4 s and the next half in 2 s . What is its average angular velocity?
- A \(\frac{4 \pi}{9} \mathrm{rad} / \mathrm{s}\)
- B \(\frac{\pi}{6} \mathrm{rad} / \mathrm{s}\)
- C \(\frac{2 \pi}{3} \mathrm{rad} / \mathrm{s}\)
- D \(\frac{\pi}{3}\)
Answer & Solution
Correct Answer
(D) \(\frac{\pi}{3}\)
Step-by-step Solution
Detailed explanation
Average angular velocity \((\omega)=\frac{\mathrm{O}_{\text {total }}}{\mathrm{t}_{\text {total }}}=\frac{2 \pi}{4+2}=\frac{\pi}{3} \mathrm{rad} / \mathrm{s}\)
