Likewise, this charge Q one will also feel a force due to this charge q two. And the force will be in the opposite direction with the same magnitude. And it's also given by this equation, Coulomb's law. So what Coulomb's Law says is the following if we place two electrons next to each other, they will repel. They will create repulsion forces. So this leads into the following fact placing electrons into the same orbital in a subshell will create repulsion forces.
