The membrane that surrounds a certain type of living cell has a surface area of 4.60 10-9 m2 and a thickness of 9.60 10-9 m. Assume that the membrane behaves like a parallel plate capacitor and has a dielectric constant of 4.60.

The potential on the outer surface of the membrane is +61.2 mV greater than that on the inside surface. How much charge resides on the outer surface?
