Two Satellites Are Placed in Geosynchronous Orbits,orbits with a Period $\frac { 1 } { 9 }$

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.Satellite B has three times the mass of satellite A.What is the relationship between the magnitudes of the gravitational forces of the Earth on the two satellites?

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