Net Electric Charge...Please help!!! 1. The problem statement, all variables and given/known data What is the net electric force on charge A? (s=1.41 cm, q1=1.1 nC, q2=0.72 nC, q3=5.21 nC. Force is positive if it points to +x direction.) 2. Relevant equations F = (K * Q * Q) / r^2 3. The attempt at a solution F2on1 = (K * Q1 * Q2) / r^2 = 3.59 x 10^-5 N F3on1 = (K * Q2 * Q3) / 2r^2 = 6.486 x 10^-5 N F3on1 - F2on1 = 2.9 x 10^-5 N It's not right...what am I doing wrong?
