Part $($b$)$

Using the electric field you found in part A $,$ calculate the charge density, $($charge per unit area$),$ on the plates in $\frac{C}{m^2}.($Hint: The E field near to a single plate of charge having a uniform charge density $,$ is $2k_C$ where $k_C=9{10}^{9}N-\frac{m^2}{C^2}.)$

Your answer appears to be off by a factor of ${10}^n,$ where $n$ is an integer value. Ensure you have represented the number in the correct units.

Part $($c$)$

Using the charge density you found in B$,$ calculate the magnitude of the charge on each side of the piece of cell membrane we are modeling and the net charge on the piece of the membrane. Give your answer in coulombs.
