I have this standard homework problem to find the electrical field at a point.(adsbygoogle = window.adsbygoogle || []).push({});

I figured out most of the math like the x and y components of the E Field from the two charges acting on the point. I also have the correct answer and i don't understand why the x components of the electrical charge cancel and all that's left is the sum of the two y components.

Here's drawing of problem and me figuring out direction of e fields: http://focusedwolf.googlepages.com/work2.bmp [Broken]

It just looks to me like the y components should cancel and it's the sum of the x components.
