Question When a nerve impulse propagates along a nerve cell, the electric field within the cell membrane changes from 7.0 x 10^5 N/C (pointing in one direction) to 3.0 x 10^5 N/C (pointing in the other direction). By approximating the cell membrane as a parallel-plate capicator, find the magnitude of the change in charge density on the walls of the membrane
