Consider two satellites

{S}_{1}

and

{S}_{2}

with periods of revolution

1hr

and

8hr

respectively revolving around a planet in circular orbits. The ratio of angular velocity of satellite

{S}_{1}

to the angular velocity of satellite

{S}_{2}

is:

Options

A $8: 1$
B $2: 1$
C $1: 4$
D $1: 8$

Correct answer

A. $8: 1$

Step-by-step solution

$\dfrac{{T}_{1}}{{T}_{2}} = \dfrac{1}{8}$

$\dfrac{2\pi / {\omega}_{1}}{2\pi / {\omega}_{2}} = \dfrac{1}{8}$

$\dfrac{{\omega}_{1}}{{\omega}_{2}} = \dfrac{8}{1}$
