Two Satellites Are Placed in Geosynchronous Orbits, Orbits with a Period

Multiple Choice

Two satellites are placed in geosynchronous orbits, orbits with a period of 24 hours, where each satellite hovers over a spot on the Earth's equator.

A) FB = $\frac{1}{9}$ FA.
B) FB = $\frac{1}{3}$ FA.
C) FB = FA.
D) FB = 3FA.
E) FB = 9FA.
