Angular velocity, Angular acceleration

Two particles A and B are moving in uniform circular motion in concentric circles of radii rA and rB with speed vA and vB respectively. Their time period of rotation is the same. The ratio of angular speed of A to that of B will be


 Time period, T=2πω  As TA=TB  So, 2πωA=2πωB  or  ωA:ωB=1:1
