Final Answer:
The gravitational pull of the Earth is strongest on any object located closest to its center. Therefore, the satellite experiencing the strongest gravitational pull is the one in the geostationary orbit, as it is situated directly above the equator.
Step-by-step explanation:
Gravitational Pull of Earth: The strength of gravity depends on the distance between two objects and their masses. Objects experience the strongest gravitational pull when they are closest to the center of mass, which, for Earth, is at its core.
Geostationary Orbit: Satellites in geostationary orbit orbit the Earth directly above the equator at an altitude where their orbital period matches Earth's rotation period. This means they stay fixed relative to a point on Earth's surface. As they are positioned directly above the equator, they are closest to Earth's center, experiencing the strongest gravitational pull.
Alternative Orbits: Satellites in other orbits, like low Earth orbit or medium Earth orbit, are not as close to the Earth's center as geostationary satellites, so they experience a slightly weaker gravitational pull.
