If a particle moves with a uniform angular velocity $$\omega $$ radians/sec along the circumference of a circle of radius r, the equation for the velocity of the particle, is

A. $${\text{v}} = \omega \sqrt {{{\text{y}}^2} - {{\text{r}}^2}} $$

B. $$\overline {\text{y}} = \omega \sqrt {{\text{y}} - {\text{r}}} $$

C. $${\text{v}} = \omega \sqrt {{{\text{r}}^2} + {{\text{y}}^2}} $$

D. $${\text{v}} = \omega \sqrt {{{\text{r}}^2} - {{\text{y}}^2}} $$
