1. The problem statement, all variables and given/known data 2. Relevant equations kq1q1/r^2 k being 8.98755 x 10^9 3. The attempt at a solution I found the 3 forces between the 3 charges using the above equation. I split up the forces into x and y compnents. Added the sum of the y's and the x's. Used Pythagorean theorem to find the resulting force. I could not get the correct answer.
