The charge q2 is now replaced by two charges q3 and q4 which each have a magnitude of -1.85 µC, half of that of q2.
The charges are located a distance a = 2.2 cm from the origin along the y-axis as shown. What is APE, the change in
potential energy now if charge q1 is moved from point P to point R?
