Thanks everybody! All I had to do was put a negative on it.

Sorry, I meant to say the forces have equal magnitude and opposite directions. What word? I'm really not getting this. I basically did the same thing that Cyclovenom did. I assumed that the sign of one charge would be the same as the 3rd one, and that the other would be opposite...

The question says particle 3 is free to move, but the net electrostatic force on it from particles 1 and 2 happens to be zero. Doesn't that mean that the forces have to be equal but with opposite charges?

The entire question is this: Three charged particles lie on an x axis. Particles 1 and 2 are fixed in place. Particle 3, is free to move, but the net electrostatic force on it from particles 1 and 2 happens to be zero. If the distance between particles 1 and 2 is equal to the distance...

I'm stuck on what I think should be a fairly easy question. The question is that there are three charged particles in a line, equidistant (distance L) from each other. From left to right, we'll call them 1, 2, and 3. 1 and 2 are fixed in place, but 3 is free to move. However, the net charge...
