Here's the problem: Two points are in an E-field: Point 1 is at (x1,y1) = (4,4) in m, and Point 2 is at (x2,y2) = (13,13) in m. The Electric Field is constant, with a magnitude of 65 V/m, and is directed parallel to the +x-axis. The potential at point 1 is 1000 V. Calculate the potential at point 2. --------------- IT IS ABSOLUTELY SICKENING How Many Times I Attempted this Seemingly Easy Problem And Got it WRONG...so apparently, this isn't as easy as I thought ! I KNOW this problem Has to utilize the formula V = Ed (or perhaps V = Edcos(theta) ???) for d i get sqrt((13-4)^2 + (13-4)^2) = 12.7279 and E is given soooooooooo... for the change in potential i get 827. I then add that to the potential of point 1 to get the potential of point 2 and I get 1827. But apparently that's wrong. So are the answers 1000, 1585, and 1292 which I got from slightly tweaking the main formula in different ways. I have no clue what else to try...any help ?
