The membrane surrounding a living cell consists of an inner and anouter wall that are separated by a small space. Assume that themembrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has amagnitude of 7.50 10-6 C/m2.
a) What is the magnitude of the electric field within the cellmembrane?
b) Find the magnitude of the electric force that would be exertedon a potassium ion (K+; charge = +e) placedinside the membrane.
