The inner and outer surfaces of a cell membrane carry a negative and a positive charge, respectively.

Question:

The inner and outer surfaces of a cell membrane carry a negative and a positive charge, respectively. Because of these charges, a potential difference of about 0.070 V exists across the membrane. The thickness of the cell membrane is 8.0 × 10-9 m. What is the magnitude of the electric field in the membrane?
