Twо pоints, а аnd b, аre lоcated 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]
