Let A = (1, 3/1) and B = (x2, 3/2) 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 to such a charged sheet has the same magnitude everywhere and points away from the 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 sheet, as shown in (Figure 1). choices simply change the potential by an additive constant, so the potential difference will stay the same, regardless of what point you designate as having zero potential. Part B Part C Now take the potential to be zero at y = 0 instead of at infinity. What is the value of VA at point A some positive distance y/1 from the sheet?
