The surfaces of a lipid bi-layer forming the membrane around a cell with a radius of 1.2 µm has a residual charge qr = 9x10-15 C on outside of the bi-layer, and the same amount of negative charge on the inside. What is the force in pN (x10-12 N) on a singly-charged positive ion (q =1.6 x10-19 C) located on the outer surface of this membrane? Hint: Use F = q E = q (o/e) with o = qr/A = qr/ (4Tt r²) and ɛ. = 8.85 x 10-12 F-m-1. Answer: 8.99180 F
