Homework Equations

kq1q1/r^2
k being 8.98755 x 10^9

The Attempt at a Solution

I found the 3 forces between the 3 charges using the above equation. I split up the forces into x and y compnents. Added the sum of the y's and the x's. Used Pythagorean theorem to find the resulting force. I could not get the correct answer.

Well since you didn't post your calculation and you did do the question how you were supposed to do it.The most I can say is that you probably drew the forces going in the wrong direction. Like charges repel and unlike attract.

My resulting vector was pointing towards the first quadrant. Is that right?
