consider three charges: +Q, -Q, q
where the center charge is equidistnat from the other two. assum that the two Qs cannot move. you also want to charge q to be at rest. if q=-8.0 nC, find Q+
You don't have to solve it but can you lead me in the right direction to solve the problem. i know i have to use the formula: f=kQ1Q2/r^2 (coulomb)
But can you just give me steps on how to do it.

As I understand your question, there is no solution. q is +, so will be repelled by +Q, but attracted by -Q. Because -Q is nearer, the force of attraction will be always greater than the force of attraction from the further +Q.
