Ok, i'm inexperienced with the latex code, so excuse me.

I'm trying to derive the expression for the electric field at a point, along the perpendicular bisector of a charged rod, of known total charge, length L, a perpendicular distance y from the rod.

The horizontal components cancel,

[tex]

\frac{qy}{4\pi \varepsilon_0 L} \int_0^L \frac{dx}{((\frac{L}{2}-x)^2 +y^2)^{3/2}}

[/tex]

I don't think this is right, because that seems a nasty integral. Any ideas?

Apologies if you think this is the wrong section. Thanks.
