NEET2019PhysicsMotion in Two DimensionsActual

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,

Options

  1. Ar A : r B
  2. Bv A : v B
  3. Cr B : r A
  4. D1 : 1

Correct answer

D. 1 : 1

Step-by-step solution

T A = T B ω A ω B = T B T A Same time period ⇒ same angular speed.
