The radii of circular orbits of two satellites A and $B$ of the earth are $4 R$ and $R$ , respectively. If the speed of satellite $A$ is $3 v$ , then the speed of satellite $B$ will be

Options:

Answer:

Solution:

$Orbital velocity of satellite v = \frac{GM}{r} \Rightarrow ∴ ∴ \frac{v _{A}}{v _{B}} = \frac{r _{B}}{r _{A}} = \frac{R}{4 R} = \frac{1}{2} \frac{v _{A}}{v _{B}} = \frac{3 v}{v _{B}} = \frac{1}{2} v_{B} = 6 v$
