Two particles A and B are moving in uniform circular motion in concentric circles of radii $$r_A and r_B$$ with speed $$v_A and v_B$$ respectively. Their time period of rotation is the same. The ratio of angular speed of A to that of B will be:

A

$$v_A : v_B$$

B

$$r_B : r_A$$

C

$$1 : 1$$

D

$$r_A : r_B$$
