Find the magnitude of the change in charge density

Reference no: EM13284929

When a nerve impulse propagates along a nerve cell, the electric field within the cell membrane changes from 7.2×10^5 N/C in one direction to 2.9×10^5 N/C in the other direction. Approximating the cell membrane as a parallel-plate capacitor, find the magnitude of the change in charge density on the walls on the cell membrane.
