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
