Argh... I figured out what I did "wrong" in the end. I put that k = 8.99 * 10^9, so instead of writing down k, I wrote down the numerical value. And the system kept telling me that it was wrong. So the answer was: F_q_3x = 2[(k)(q)(-Q)/(a^2 + x^2) * x/(sqrt(x^2 + a^2))] That's...

I don't understand. Since I'm looking for the x-component of the force, I'd need the force directed along the x-axis, right? If the "height" of the triangle of one force is a, and the "base" is x, then the hypotenuse of the triangle would be sqrt(a^2 + x^2), right? Why would I need the...

Homework Statement Two positive point charges q are placed on the y-axis at a and -a. A negative point charge -Q is located at some point x on the +x-axis. Find the x-component of the net force that the two positive charges exert on -Q. Express your answer in terms of the variables q...
