conductor G 40 V 30V 20 V 10 y conductor QV - 10 VAN -30 V #1. The electric potential diagram above shows equipotentials for a 2-dimensional region of space. a. At which point-A, B, C, D, or E-would an electron have the highest electric potential energy? Briefly explain your answer. Answer:. At A. Electron has highest potential energy where electric potential is lowest, the opposite of what a positive test charge experiences. #2. In which general direction does the electric field point in this diagram? Briefly explain your answer. Answer: The electric field points from upper left to lower right. Electric field lines point in the direction of high-to-low electric potential. #3. Based on the equipotentials, draw a sketch on the diagram above of the electric field, including at least five field lines Answer: Field lines should be perpendicular to equipotentials
