In uniform circular motion of radius $r$ and speed $v$, the angular speed $\omega$ is
A$\omega=vr$
B$\omega=\dfrac{r}{v}$
C$\omega=\dfrac{v}{r}$
D$\omega=v^2r$
Answer & Solution
Correct answer: C. $\omega=\dfrac{v}{r}$
For motion along a circle, linear speed and angular speed are related by $v=r\omega$. Therefore $\omega=\dfrac{v}{r}$.
