Two satellites $A$ and $B$ go round a planet $P$ in circular orbits having radii $4 R$ and $R$ respectively. If the speed of satellite $A$ is $3 V$ , the speed of the satellite $B$ will be.

Options:

Answer:

Solution:

$v = \sqrt{\frac{G M}{R}}$ $\Rightarrow$ $\frac{v_{A}}{v_{B}} = \sqrt{\frac{R_{B}}{R_{A}}} = \sqrt{\frac{R}{4 R}}$ $= \frac{1}{2}$
∴ $\frac{v_{A}}{v_{B}} = \frac{3 V}{v_{B}} = \frac{1}{2}$ $∴ v_{B} = 6 V$
