The cell membrane is to be considered a thin layer enveloping a cell. In the static case, the membrane has a charge distribution of -2.5x10−6 C/m2 on the inner surface and +2.5x10−6 C/m2 on the outer surface. [Assume 0 net charge enclosed within the cell from the center to but not including the interior of the cell membrane.] Is there any electric field inside of the cell? If non-zero, calculate the electric field magnitude. Also, is there any electric field within the cell membrane.   If non-zero, calculate the electric field magnitude. Show all work and answer each part of the question.
