The equipotential lines in a region of electric field are shown in the diagram below. For each path indicated below, what is the work done by the electric field in moving a charge q = +3.7×10−7 C along that path? Here V0 = +130 V. (a) from A to B WAB = ∫J (b) from A to C WAC = J (c) from A to D WAD = J (d) from D to C WDC = J
