For 10 points, name this quantity that is measured in coulombs, symbolized q, and comes in positive and negative forms.
The Poisson-Boltzmann equation computes the electrostatic potential given the density of this quantity; linearization of that equation yields the Debye-Huckel equation. Magnetic force is equal to this quantity times the cross product of velocity and magnetic field, and the electric flux is equal to this quantity over epsilon-naught.
