V =( GM / r ) ⇒ ( V 1/ V 2)=√(800/3200)=(1/2)

Q. Two satellites $S_{1}$ and $S_{2}$ are revolving in circular orbits around a planet with radius $R_{1} = 3200 km$ and $R_{2} = 800 km$ respectively. The ratio of speed of satellite $S_{1}$ to the speed of satellite $S_{2}$ in their respective orbits would be $\frac{1}{x}$ where $x =$

$V = \frac{GM}{r} \Rightarrow \frac{V _{1}}{V _{2}} = \frac{800}{3200} = \frac{1}{2}$
