## Can Coulomb force negative?

We have another universal fact that like charges repel and unlike charges attract. The force between two like charges is repulsive and unlike charges is attractive. That is, the Coulomb force between opposite charges is negative. Therefore, we found that Coulomb force can be negative.

## What is epsilon not?

Epsilon Naught is an ideal physical constant that is the representative of the absolute dielectric permittivity of a vacuum. In other words, Epsilon Naught quantifies a vacuum’s ability to facilitate the flowing of electric field lines through it.
