... 4 The net electric force on the central charge is then F = 2qE = 2.9 × 10−5 N x̂ − 1.6 × 10−5 N ŷ 2.a. First, it is obvious that −q experiences no net electric force. By symmetry, the electric force on one of the two +Q’s is zero if and only if the other is zero. Therefore, we can just focus on one ...
