At a corner of a 30 mm x 40 mm rectangle is placed a charge of -40µC and at the two adjacent corners are charges of +20µC, as shown in the figure. Determine: a. The potential at the 4ª corner P. b. The potential at the center of the rectangle. c. The work that must be done by an external force to bring a charge q1 = +5µC from the center of the rectangle to the 4th corner P. 91 = +20 µC 92 = -40 µC 30 mm P 40 mm '43 = +20 µC
