Question: Consider a membrane of some cell ( which we will treat as a parallel plate capacitor ) . It has a potential difference of 7

Consider a membrane of some cell (which we will treat as a parallel plate capacitor). It has a potential difference of 70 mV across its lipid bilayer (which is 5 nm thick). It was a charge density of 1 mC/m2. This is a charge per area. What is the relative permittivity r of the membrane material?
