MCQ
If $\text{OP}$ makes $4$ revolutions in on second the angular velocity in radians per seconds is:
  • A
    $\pi$
  • B
    $2\pi$
  • C
    $4\pi$
  • $8\pi$

Answer

Correct option: D.
$8\pi$
$\text{Angular velocity}=\frac{\text{Distance}}{\text{Time}}$
$=\frac{4\times2\pi}{1}$
$=8\pi\ \text{radians}$
