Manipal MET2010PhysicsMotion in Two Dimensions

Two cars A and B move along a concentric circular path of radius r_A and r_B with velocities v_A and v_B maintaining constant distance, then v_A v_B is equal to

Options

  1. Ar_B r_A
  2. Br_A r_B
  3. Cr_A^2 r_B^2
  4. Dr_B^2 r_A^2

Correct answer

B. r_A r_B

Step-by-step solution

Angular velocity is constant. v r or v_A v_B = r_A r_B
