A positive point charge q1 = 2.30uC is located at the origin (x=0, y=0). The charge is held fixed. Another point charge q2 = 5.60uC starts at the point (0.180 m,0). What is the magnitude of the work required to move q2 to (0,0.370 m) (in J)? How do I do this? I know W =Fd, but I don't think I can use the equation F = (k1q2)/r^2, because the distance is constantly changing. Can anyone at least give me a hint or some insight?
