8. Two point charges, q1=q2=13nC, are located on the x-axis and is 8 meters apart. Assuming that q1 is located at the origin: a. Find the work that must be done by an external force to bring a third point charge q3 =-13nC from infinity to x-11m. b. Find the total potential energy of the system of three charges.
