Question

Nerve cells are long, thin cylinders along which
electrical disturbances (nerve impulses) travel. The cell membrane
of a typical nerve cell consists of an inner and an outer wall separated by a distance of 0.10 mm. The electric field within the cell
membrane is 7.0 * 105
N>C. Approximating the cell membrane
as a parallel-plate capacitor, determine the magnitude of the
charge density on the inner and outer cell walls.
