using the instructions in the image, what is the work done by the electric force to move a 1C charge from A to B?

The dashed curves in the diagram represent cross sections of equipotential surfaces drawn in 1-volt increments. The set of curves is surrounded by a rectangle. The equipotentials are closer to each other at the lower left corner of the rectangle and are farther apart as they approach the right upper corner of the rectangle. The nearest curve to the left lower comer is labeled as -3 volts, and the nearest curve to the nght upper corner is labeled as 2 volts. Point C is placed halfway between curves labeled as -2 volts and -1 volt nearby the lett vertical side of the rectangle. Point D is placed on the curve labeled as 0 volts nearby the lower side of the rectangle. Point B is placed on the curve labeled as 1 volt nearby the left upper corner of the rectangle and point A is placed on the same curve as point B in the center of the rectangle
