A satellite $S_{1}$ of mass $m$ is moving in an orbit of radius $r$ . Another satellite $S_{2}$ of mass $2 m$ is moving in an orbit of radius $2 r$ . The ratio of time period of satellite $S_{2}$ to that of $S_{1}$ is

Options:

Answer:

Solution:

According to Kepler's Law of periods: $T^{2} \propto R^{3}$ Therefore, $\frac{T _{2}}{T _{1}} = (\frac{2 r}{r})^{\frac{3}{2}} = \frac{2 2}{1}$
