Satellites - Orbital Velocity & Period

The distance of the two planets A and B from the sun are ' $r_A$ ' and ' $r_B$ ' respectively such that $r_B = 100\,r_A$ . The ratio of the speed of planet A to that of planet B is (both the planets are revolving around the sun)

Show answer and solution

Answer: (c)

Orbital speed $v \propto \frac{1}{\sqrt{r}}$ .
$\frac{v_A}{v_B} = \sqrt{\frac{r_B}{r_A}} = \sqrt{100} = 10$
So the answer is (c) $10$ .
