Two satellites, one in geosynchronous orbit (t = 24 hrs) and one with a period of 12 hrs, are orbiting earth. how many times larger than the radius of earth is the distance between the orbits of the two satellites. (mass(earth) = 5.98 × 1024 kg, g = 6.67 × 10–11 n·m2, g = 9.81 m/s2, radius(earth) = 6.38 × 106 m)
