Acell membrane consists of an inner and outer wall separated by a distance of approximately 10nm. assume that the walls act like a parallel plate capacitor, each with a charge density of 10−5c/m2, and the outer wall is positively charged. although unrealistic, assume that the space between cell walls is filled with air.

Electric field,

Explanation:

It is given that,

Distance between inner and outer wall of a cell membrane, d = 10 nm

Charged density of a parallel plate capacitor,

It is assumed to find the electric field between the membranes. We know that the electric field between the parallel plates is given by :

E = 1129943.50 N/C

or

So, the electric field between the cell membranes is . Hence, this is the required solution.

conduction, convection, radiation

reserve is the answer
