Question 4...A cell membrane has a surface area of 1.3 x 10-7m², dielectric constant K = 5.2, and a thickness of 7.2nm. A potential difference of 70 mV is established across the cell membrane. The membrane is thinenough to be modelled as a parallel plate capacitor.12(a) Calculate the magnitude of the charge on each surface of the membrane.(b) Estimate the number of ions on the membrane surface assuming that the ions are singly charged.(c) Calculate the electric field in the membrane.

Since the membrane can be modelled as a parallel plate capacitor, its free space capacitance is…
