If the areal velocity of one planet is 2 times the areal velocity of other planet, then find the ratio of their radii of circular motion around the sun.

Answer:

4.00

Solution:

$\frac{d A}{d t} = \frac{1}{2} r v$

$v = \frac{GM}{r}$

$\frac{d A}{d t} \propto r$

If areal velocity ratio is 2, the radius ratio is 4.
