Some cell membranes in the human body have a layer of negative charge on the inside surface and a layer of positive charge of equal magnitude on the outside surface. Suppose that the charge density on either surface is ± 0.50×10−3 C/m2, the cell membrane is 5.00 nm thick, and the cell membrane is made up of tissue with a dielectric constant of 5.40.
A) Find the magnitude of E in the membrane between the two layers of charge.
E=? V/m
B) Find the potential difference between the inside and the outside of the cell. Which is at the higher potential?
ΔV=?V
C) A typical cell in the human body has a volume of 10−16m3 . Estimate the total electric-field energy stored in the wall of a cell of this size. (Hint: The cell membrane is very thin. Assume that the cell is spherical, and calculate the area of the cell membrane.)
U=?J
I am really having trouble with this problem; nothing i try is correct. I appreciate the help.

Many cells in the human body maintain an electric potential difference across their cellular membranes, typically through the use ion-specific pumps and channels that generate an excess of negative charges on the inside of the cellular membrane and an excess of positive charges on the outside. Let us estimate the total energy stored in the human body by this type of charge separation. Part a Different cells can have vastly different cell sizes; but as an approximation, let us assume...

The fluids inside and outside a cell are good conductors separated by the cell wall, which is a dielectric. Thus the cell has capacitance; charge may be stored on its inner and outer surfaces (see the figure below). It is a good approximation to treat the thin charged layer as a parallel-plate capacitor. Typically the wall is 9.50 x 10-9 m thick and has a dielectric constant of 5.00. (everybody's responses to this question before were incorrect so I need...

Cell membranes (the walled enclosure around a cell) are typically about d = 7.0 nm thick. They are partially permeable to allow charged material to pass in and out, as needed. Equal but opposite charge densities build up on the inside and outside faces of such a membrane, and these charges prevent additional charges from passing through the cell wall. We can model a cell membrane as a parallel-plate capacitor, with the membrane itself containing proteins embedded in an organic...

Cell Membranes and Dielectrics Many cells in the body have a cell membrane whose inner and outer surfaces carry opposite charges, just like the plates of a parallel-plate capacitor.
