Two satellites $A$ and $B$ , have the ratio of their masses as $m_{A} : m_{B} = 3 : 1$ , are in the circular orbits of radii $r$ and $4 r$ respectively. The ratio of total mechanical energy of $A$ to that of $B$ is

Options:

Answer:

Solution:

$E = - \frac{G M m}{2 r}$

or $E \propto \frac{m}{r}$

$∴ \frac{E_{1}}{E_{2}} = \frac{m_{1}}{m_{2}} \times \frac{r_{2}}{r_{1}} = \frac{3}{1} \times \frac{4}{1} = \frac{12}{1} = 12$
