Imagine a solar system in which all of the planets orbit a star, and this star is more massive than any of the other planets. additionally, all of the planets have the same mass, but planet a is closer to the star than planet b. which of the following is also true?
question options:
1. the gravitational pull between the star and planet a is the same as the pull between the star and planet b because planet a and planet b have the same mass.
2.the gravitational pull between the star and planet a is the same as the pull between the star and planet b because the star is so much larger.
3.the gravitational pull between the star and planet b is greater than the pull between the star and planet a because planet a is closer to the star than planet b.
4.the gravitational pull between the star and planet a is greater than the pull between the star and planet b because planet a is closer to the star than planet b.

4.The gravitational pull between the star and Planet A is greater than the pull between the star and Planet B because Planet A is closer to the star than Planet B.

Explanation:

The planets are kept in orbit around the star due to a mutual action, that is, due to the gravitational attraction between the star and the planets.

The law of gravitational attraction, considered by Isaac Newton, says that bodies are attracted "in the direct ratio (multiplication) of the masses and in the inverse ratio (division) of the square of the distance". This means that the attraction is greater the greater the mass, and decreases when the distance increases.

In this case, we can conclude that the star's gravitational attraction force is greater, since it is more mass than the planets (which have equal masses), in addition, the planets that are more distant have a lower gravitational attraction than the nearest planets . That is, the gravitational attraction between the star and Planet A is greater than the attraction between the star and Planet B because Planet A is closer to the star than Planet B.
