Three point charges are located on the x-axis. The first charge q1 = 10.0μC at x =1.0m; the second charge, q2 =20.0μC, is at the origin, and the third charge is q3=30.0μC is located at x =2.00m.
A. Decide the potential energy of this arrangement
B. Decide the magnitude and direction of the electric field at x = -5.00m
