Find the radius r of the orbit of a geosynchronous satellite that circles the earth. (note that r is measured from the center of the earth, not the surface of the earth.) use the following values if needed in this problem:
1) the universal gravitational constant g is 6.67×10−11nm2/kg2.
2) the mass of the earth is 5.98×1024kg.
3) the radius of the earth is 6.38×106m.
