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 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. Express your answer in J.
