Imagine two artificial satellites orbiting Earth at the same distance. One satellite has a greater mass than the other one. Which of the following would be true about their motion?

1. The satellite with the greater mass is being pulled toward Earth with less of a force than the other satellite.
2. The satellite with the greater mass is being pulled toward Earth with greater force than the other satellite.
3. The two satellites are being pulled with an equal force by the moon.
4. The two satellites are being pulled toward Earth with equal force.

Answer (3)

The satellite with the greater mass is being pulled toward Earth with greater force than the satellite with less mass is.
But if they're both orbiting Earth at the same distance, then they both orbit in the same time. That's how "space walks" work. Even though the astronaut has a lot less mass than the Shuttle or the International Space Station has, they're both orbiting Earth at the same distance, so the time it takes both of them to orbit is the same, and the astronaut can float beside the spacecraft.

The satellite with the greater mass experiences a greater gravitational force while orbiting Earth at the same distance. However, both satellites will have the same orbital velocity and period. Therefore, the correct answer is that the satellite with greater mass is being pulled with greater force.
