Problem
A communications satellite in a geostationary orbit around the Earth is moving at a constant speed. At any moment, the resultant force on the satellite is
(1) zero.
(2) equal to the gravitational force on the satellite.
(3) equal to the vector sum of the gravitational force on the satellite and the centripetal force.
(4) equal to the gravitational force on the satellite minus the centripetal force.
