MCQ
A particle is describing the circular path of radius 20 m in every 2 s. The average angular speed of the particle during 4 s is
  • A
    $20 \pi rad s ^{-1}$
  • B
    $4 \pi rad s ^{-1}$
  • ✓
    $\pi rad s ^{-1}$
  • D
    $2 \pi rad s ^{-1}$
✓

Answer

Correct option: C.
$\pi rad s ^{-1}$
(C)
$\omega=\frac{\text { angle des cri bed } }{\text { ti maken }}=\frac{2 \pi}{2}=\pi rad / s$
