If OP makes 4 revolutions in one second,


If OP makes 4 revolutions in one second, the angular velocity in radians per second is

(a) π

(b) 2 π

(c) 4 π

(d) 8 π


(d) 8 π

Angular velocity $=\frac{\text { Distance }}{\text { Time }}$

$=\frac{4 \text { revolutions }}{1 \text { second }}$

$=\frac{4 \times 2 \pi}{1} \quad(\because 1$ revolution $=2 \pi$ radians $)$

$=8 \pi$ radians per second
