Physics - Gravitation Question with Solution | TestHub

Orbital speed,${\mathrm{v}}_0=\sqrt{\frac{\mathrm{G}\mathrm{M}}{\mathrm{r}}}$; so speed of satellite decreases with the increase in the radius of its orbit. We need more than one satellite for global communication. For stable orbit, the plane of the satellite must through the center of earth. So, only (Geostationary satellites are launched in the equatorial plane) is correct.
