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,
  1. rA:rB
  2. vA:vB
  3. rB:rA
  4. 1:1

Solution

TA=TBωAωB=TBTA
Same time period ⇒ same angular speed.
