The inner аnd оuter wаlls оf а cell membrane can be mоdeled as a charged parallel plate capacitor. Suppose that the inner and outer walls of a cell membrane are separated by a distance of 9.5x10-9m and that the inner and outer walls each have a charge density of 2x10−5C/m2, with the outer wall being positively charged and the inner wall being negatively charged. Find the potential difference (aka the voltage difference) between the inner and outer wall? Express your answer in Volts but do not include the V in your answer.
