Question 304: Gravitation

Question

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

Accepted Answer

$$\begin{aligned}
\frac{E_A}{E_B} & =\frac{M_A}{M_B} 	imes \frac{r_B}{r_A} \quad \ldots\left(E \propto \frac{M}{r}ight) \
& =\frac{3}{1} 	imes \frac{4 r}{r} \
\frac{E_A}{E_B} & =\frac{12}{1}
\end{aligned}$$
