Kepler's Laws & Planetary Motion

The distance between Sun and Earth is R. The duration of year if the distance between Sun and Earth becomes 3R will be:

Show answer and solution

Answer: (d)

  1. Kepler's third law: T∝R3/2T \propto R^{3/2}.
  2. T′=1×33/2=33T' = 1 \times 3^{3/2} = 3\sqrt{3} years
  3. So the answer is (d) 333\sqrt{3} years.
