I don't remember using that formula. I've been using the formula Electric field = Cq/r^2, C being a constant 9.0 x 10^9.

I did, but I'm not not getting the correct answer, which should be 5.8 x 10^5. I'm not sure how they got that, which is what I'm essentially asking for: The process. I end up having to add -222 222.2222 + 8.0 x 10^5, however it's obviously not going to be the right answer.

What are the magnitude and direction of the electric field strength at point Z in the following: Point X, q1 = -2.0 x 10^-5 and it is 60 cm to the left of point Y, q2 = 8.0 x 10^-6, which is 30 cm to the left of Z. Essentially, this is what it looks like: X-------Y--Z

How did you solve for part B using Eg + Ek = Ek'?
