Three point charges are fixed in the x-y plane, as shown in the figure. The charges are QA = +[q] × 10-4 C, QB = +[q] × 10-4 C, and QC = –[q] × 10-4 C. The (x, y) coordinates of each charge are indicated in the figure, with coordinates given in meters. What is the electric potential energy of the system (in J)?

Two points, a and b, are located in the x-y plane, with coordinates given in meters (m), as shown in the figure. A uniform electric field of magnitude 5000 V/m is directed along the +x axis. A charged particle with charge Q = +[q] × 10-4 C is moved from point a to point b by an external force. The particle starts and ends at rest. How much work does the external force do on the particle (in J)? Note: The result may be positive or negative. [Hint: external work = change in electric potential energy]
