The period of revolution of planet A around the sun is 8 times that of planet B. How many times the distance of A from the sun is greater than that of B from the sun?

Options

  1. A5 times
  2. B2 times
  3. C3 times
  4. D6 times

Correct answer

C. 3 times

Step-by-step solution

aligned & ( R ₁ R ₂ )^3= ( T ₁ ~T ₂ )^2=(8)^2=64 & R ₁ R ₂ =(64)^ 1 3 =4 & R ₁=4 R ₂ & R ₁- R ₂=4 R ₂- R ₂=3 R ₂ aligned
