Question

the membrane surrounding a living cell consists of an innerand an outer wall that are seperated by a small space. assume thatthe membrane acts like a parallel plate capacitor in which theeffective charge density on the inner and outer walls has themagnitude of 6.40*10-6 c/m2 a. what is the magnitude of the electric field within the cellmembrane? b.find the maggnitude of the electric force that would beexerted on a potassium ion(k+;charge=+e) placed inside themembrane? the membrane surrounding a living cell consists of an innerand an outer wall that are seperated by a small space. assume thatthe membrane acts like a parallel plate capacitor in which theeffective charge density on the inner and outer walls has themagnitude of 6.40*10-6 c/m2 a. what is the magnitude of the electric field within the cellmembrane? b.find the maggnitude of the electric force that would beexerted on a potassium ion(k+;charge=+e) placed inside themembrane? a. what is the magnitude of the electric field within the cellmembrane? b.find the maggnitude of the electric force that would beexerted on a potassium ion(k+;charge=+e) placed inside themembrane?

Explanation / Answer

Effective charge density on the inner and outer walls has themagnitude = 6.40*10-6 c/m2 (a). the magnitude of the electric field within the cellmembrane = / where = permitivity of free space = 8.85 * 10-12 C 2 / N m 2 substitue values weget answer (b). the maggnitude of the electric force that would beexerted on a potassium ion(k+;charge=+e) placed inside the membraneis F = E q where q = charge = 1.6 * 10 -19 C substitue values we get answer substitue values weget answer (b). the maggnitude of the electric force that would beexerted on a potassium ion(k+;charge=+e) placed inside the membraneis F = E q where q = charge = 1.6 * 10 -19 C substitue values we get answer
