Two satellite A and B go round a planet in circular orbits having radii 4 R and R respectively. If the speed of A is 3 v , the speed of B will be :

Options

  1. A3 v
  2. B6 v
  3. C4 3 v
  4. D12 v

Correct answer

B. 6 v

Step-by-step solution

aligned & v = G M R & v_A v_B = R_B R_A = R 4 R = 1 2 & v_B=2 v_A=6 v aligned
