The membrane that surrounds a certain type of living cell has a surface area of 7.1 x 10-9 m2 and a thickness of 1.5 x 10-8 m. Assume that the membrane behaves like a parallel plate capacitor and has a dielectric constant of 4.4. (a) The potential on the outer surface of the membrane is 75.9 mV greater than that on the inside surface. How much charge resides on the outer surface
