particle 1 of charge q1 (at origin) and particle 2 of charge q2 = 3q1, are held at separation L on an x axis. If particle 3 of unknown charge q3 is to be located such that the net electrostatic force on it from particles 1 and 2 is zero, what must be the (a) x and (b) y coordinates of particle 3?

2. Relevant equations

F=k|q1||q2|/d^{2}

3. The attempt at a solution

I assumed q1 and q2 are like charges so I put q3 in the middle. This could be my mistake since im getting incorrect answers for x, I do know y = 0.

If q3 does belong between the two charges on the X axis, then I am not setting up my d^{2}part of Coulombs law. Could someone point me to the right direction?

Net Force = 0

F_{31}=k|q3||q1|/?^{2}

F_{32}=k|q3||q2|/?^{2}
