1. We know the thickness of the cell membrane is 8.0 nm.

Potassium ions (K+) move across a 8.0-nm-thick cell membrane from the inside to the outside. The potential inside the cell is –75.0 mV, and the potential outside is zero. What is the change in the electrical potential energy ?Uelectric of the potassium ions as they move across the membrane?
