Satellite Energy & Weightlessness

Two satellites A and B having ratio of masses $3 : 1$ are revolving in circular orbits of radii ' $r$ ' and ' 4 r '. The ratio of total energy of satellites A to that of B is

Show answer and solution

Answer: (d)

$E = -\frac{GMm}{2r}$ , so $E \propto \frac{m}{r}$ .
$\frac{E_A}{E_B} = \frac{3}{1}\cdot\frac{4r}{r} = 12$ .
So the answer is (d) $12 : 1$ .
