Here's why:
* Electric force is much stronger than gravitational force: The electrostatic force between charged particles is vastly stronger than the gravitational force between them. The ratio of these forces is approximately 10^40, meaning the electric force is 10^40 times stronger than the gravitational force.
* Inverse square laws: Both electric and gravitational forces follow inverse square laws. This means they decrease proportionally to the square of the distance between the objects. However, because the electric force is so much stronger to begin with, it will always dominate, even at extremely large distances.
In summary: Even though both forces decrease with distance, the electric force is inherently so much stronger than the gravitational force between electrons that it will always be dominant, regardless of the distance between them.
