1. The problem statement, all variables and given/known data Two equal positive charges, both q = 2.0 x 10^ -6 C, interact with a third charge Q = 4.0 x 10^ -6 C, as shown above. What is the magnitude of the electric force on Q?[/B][/B] 2. Relevant equations Electric force = Kc (q1/r^2) 3. The attempt at a solution Basically, I believe that my problem is in solving the vectors. I attempted to break down the charges(it is hard to show this work on here but...) I broke it down into.... E(y) = E(1) x sin Θ(1) + E(2) x sin Θ(2) E(x) = E(1) x cox Θ(1) - E(2) sin Θ(2) I'm not sure if that makes sense, but it was all I could think of...Any help would be greatly appreciated. Thanks a lot!
