3-2.Motion in Plane
easy
If the body is moving in a circle of radius $ r$ with a constant speed $v$, its angular velocity is
A${v^2}/r$
B$vr$
C$v/r$
D$r/v$
Solution
(c)$v = r\omega $
$⇒$ $\omega = \frac{v}{r}$ = constant [As $v$ and $ r$ are constant]
$⇒$ $\omega = \frac{v}{r}$ = constant [As $v$ and $ r$ are constant]
