A uniform electric field of magnitude 300 V/m is directed in the negative y direction as shown in the figure. The coordinates of point A are (-0.200, -0.300) m and those of point B are (0.400, 0.500) m. a) Calculate the potential difference VB-VC. b) Calculate the potential difference VB-VA. c) Calculate the electric potential energy to move a charge -1C from A to B. d) Calculate the work done to move a charge -1C from C to B.
