(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two small beads having positive charges 3q and q are fixed at opposite ends of a horizontal, insulating rod, extending from the origin to the point x = d. A third small, charged bead between the two is free to slide on the rod. At what position is the third bead in equilibrium?

Can it be in stable equilibrium?

2. Relevant equations

coulombs law - F = k (|q1| |q2|)/(r^2)

3. The attempt at a solution

I am not sure what to do because I do not know if the third bead is positively or negatively charged. Unless it doesn't matter?
