Cell Membranes and Dielectrics Many cells inthe body have a cell membrane whose inner and outer surfaces carryopposite charges, just like the plates of a parallel-platecapacitor. Suppose a typical cell membrane has a thickness of8.2×10−9 m, and its inner and outer surfaces carry charge densitiesof -5.3×10−4 C/m and+5.3×10−4 C/m, respectively. In addition, assume that the material inthe cell membrane has a dielectric constant of 5.6.
Calculate the potential difference betweenthe inner and outer walls of the membrane.
Express your answer using twosignificant figures.
