All, I am wanting to see why charge density divided by e nought is equal to F/q and V/d. Unit cancellation makes it easy to equate F/q = V/d, but why is charge density alone enough to be equal to the electric field? I feel like something is missing here but I can't reconcile it nicely in my head or on paper. To be more clear, I don't understand how we get units of N/C from charge density which is C / m2. Hopefully this makes sense and someone can point me in the right direction.
