PhysicsNEET 2019Uniform circular motion and relative velocity

Motion in a Plane

Two particles A and B are moving in uniform circular motion in concentric circles of radii rAr_A and rBr_B with speeds vAv_A and vBv_B, respectively. Their time period of rotation is the same. The ratio of the angular speed of A to that of B will be:

  1. A.rA:rBr_A:r_B
  2. B.vA:vBv_A:v_B
  3. C.rB:rAr_B:r_A
  4. D.1:11:1✓

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
