Two charges, one of charge q = 4q (labeled charge 1 in the diagram), and the other of charge q = q (labeled charge 2 in the diagram), are placed a distance d apart as shown in the below diagram. d Charge 1 Charge 2 What does the position of a point charge with charge q3 = -3q that is sitting along the x- axis have to be in order to make the field at the midpoint between the two depicted charges zero? Take the origin to be at charge 1 (that is, x = = 0).
