Given that the electric field between the plates (inside the membrane) is about 107 N/C and the thickness of the membrane is about 7 nm, estimate the acceleration of the ion in nm/s2 if it were in the channel (and the channel were empty). The ion is an Na+.

Rolling down the electric hill Distributions of electric charges in a cell play a role in moving ions into and out of a cell. In this situation, the motion of the ion is affected by two forces: the electric force due to the non uniform charge distribution in the cell membrane, and the resistive force (viscosity) due to colliding with the fluid molecules. In order to begin our analysis of this, let's consider a toy model in which the ion...
