1. The problem statement, all variables and given/known data a) Find the net electric field at a point b) Find the net force experienced by a charge of -1.2 x 10-5 C placed at that point c) What would happen if the charge changed signs? 2. Relevant equations FE = qε 3. The attempt at a solution a) Solved: 6.7 x 104 N/C [E 63° N] b) FE = (6.7 x 104 N/C)(1.2 x 10-5 C) = 0.80 N [S 27° W] I'm not sure about this. I think I'm only supposed to take the magnitude of the charge into account, and figure out directions after? Also am I correct to use the net field I've already calculated? c) The magnitude of the force would remain the same, but the directions would swap since the positive charge is being attracted rather than repelled (0.80 N [E 63° N]).
