Yea I now know A, which is outside. And the equation I am using is the work function W=qEd...assuming q is the charge of the ion,1. then E=V/d...plugging all that in gets me back to the original voltage of .070V.

Homework Statement Living cells actively “pump” positive sodium ions (Na+) from inside the cell to outside the cell. It’s called pumping because it requires work to move the ions from the negatively charged inner surface of the cell membrane to the positively charged outer surface. It...

I am having the same problem. Yet out of Coulomb's e Field relationship I get the related field values however when I plus in the appropriate X values they are not equal. I agree that one is further away however that does not determine the charges location. Thanks much!
