A negatively charged object is located in a region of space where the electric field is uniform and points due north. The object may move a set distance d to the north, east, or south. Rank the three possible movements by the change in electric potential energy (Ue​) of the object. Rank from greatest increase to decrease in Ue​. To rank items as equivalent, overlap them.
(Figure 1) shows four equipotential surfaces. The positively charged particle located at Point a can move to Points b, c, or d by the paths indicated. Along which path is the greatest work done on the particle by the electric field? The work done is equal along all three paths. Path a to c Path a to d Path a to b
Diagrams 1-4 each show the same three equipotential surfaces. Which of the four diagrams correctly represents the electric field lines corresponding to the equipotential surfaces?

The graph in (Figure 2) plots the potential as a function of position along the x axis. Rank in order the magnitude of the electric field at the three points indicated. If the electric field has the same magnitude at two of the points, place them on top of each other.
