1. The problem statement, all variables and given/known data What is the net force on the bottom charge? Please give the force in Fx and Fy 2. Relevant equations F=qE E=kq/r^2 3. The attempt at a solution Fx=2.88x10^-9N Fy=-1.01x10^-4N These aren't correct. I used the equation above and used r=0.035m for both the side charges. For the top charge, r=0.05m Why is the formula not working? Thanks!
