Homework Equations
The Attempt at a Solution
I can see that the ycomponents of each particle will cancel eachother out so we are solely looking at how the xcomponent forces of each particle affect the field at the point P.
These two forces will be added together because they are pointing in the same direction. These forces also happen to have the same magnitude.
So I see the resulting electric field to be as follows,
[tex]\vec{E_{net}} =  \frac{2kq}{9} \hat{i}[/tex]
I keep getting the magnitude incorrect but I can see that I have the correct angle. (180 degrees)
What am I doing wrong for the magnitude?
EDIT: I found my mistake, I should have done,
[tex]\vec{E_{net}} = 2 \left( \frac{kqcos\theta}{25} \right) \hat{i}[/tex]
