Question

Two satellites A & B go around the earth in a circular orbits at a heigh of $R_{A} & R_{B}$ respectively from surface of the earth. Assume earth to be a uniform sphere of radius $R_{e}$ The ratio of the magnitudes of velocities of the satellite $V_{A} / V_{B}$ is

A

$\frac{R _{A}}{R _{B}}$

B

$(R_{A} / R_{B})^{2}$

C

$\frac{R _{B} + R _{e}}{R _{A} + R _{e}}$

D

$\frac{R _{B} + R _{e}}{R _{A} + R _{e}}$
