5. Particles with charges +4.00 µC and +2.00 µC are placed at the opposite corners of a rectangle as shown in the figure. (a) What is the potential at point A, relative to infinity, due to these charges? (b) If an electron was allowed to move from point A to a location halfway between point B and the +4.00 µC charge, then what final speed would that electron possess? Assume the electron started at rest and that no work was done on the electron by an force other than the electrical field force. A +4.00 µC 0.400 m +2.00 µC 0.800 m
