Okay. So I am trying to do this kind of the old fashioned way. I broke the E's down into x and y component and am adding them together component-wise.

I have found that the x components cancel out. Now I am trying to widdle down the form I have for the y components. As of now I have that:

[tex]E_y=k[\frac{-|q_1|-|q_2|}{[(d/2)^2+r^2]^{1/2}}*\frac{d/2}{[(d/2)^2+r^2]^{1/2}}[/tex]

The text has it in the form: [tex]kqd/r^3[/tex] which I am having a hard time getting.

How do I get rid of the negative sign? AND how do I make use of the fact r>>d??
