Part A Let A - (21. 8/1) and B = (2, 1/2) be two points near and on the same side of a positively charged sheet with a uniform surface charge density. The electric field E due Recall that the potential difference, the quantity asked for in Part A, is a well-defined quantity for any situation. The potential, however, is only defined once you pick a point as the zero-potential point. Different choices simply change the potential to such a charged sheet has the same magnitude by an additive constant, so the potential difference will stay the same, regardless of what point you designate as having zero potential. everywhere and points away from the sheet, as shown in (Figure.). Part B If the potential at y = co is taken to be zero, what is the value of the potential at a point V, at some positive distance y, from the surface of the sheet?
