A satellite is placed in a geosynchronous orbit. In this equatorial orbit with a period of 24 hours, the satellite hovers over one point on the equator. Which statement is true for a satellite in such an orbit?
A)There is no gravitational force on the satellite.
B)There is no acceleration toward the centre of the Earth.
C)The satellite is in a state of free fall toward the Earth.
D)There is a tangential force that helps the satellite keep up with the rotation of the Earth.
E)The force toward the centre of the Earth is balanced by a force away from the centre of the Earth.

A satellite in a geosynchronous orbit is in a state of free fall toward the Earth, meaning it is constantly falling toward the Earth due to gravity but has enough tangential velocity to keep missing it, thus maintaining its orbit.
