Question

If a body is moving in a circle of radius r meters with a constant speed v meter/sec. The angular velocity is

• A. $\frac{r}{v}$
• B. vr
• C. $\frac{v^r}{r}$
• D. $\frac{v}{r}$

Answer 1

The correct option is D $\frac{v}{r}$

If the radius is r, and the velocity is v then the angular velocity is a vector perpendicular to the plane containing the circle having magnitude $\omega =\frac{v}{r}$
