## Homework Statement

If I have a charged vertical rod and a point P which is distanced x from the perpendicular bisector of it. How do I find the electric field at P if x/(/l/2) < 1, where l is the length of the rod

## Homework Equations

## The Attempt at a Solution

I know that the equation of an electric field due to a charged rod at P is:

[tex] \frac{\lambda L}{(4 \pi \epsilon_0) * sqrt(x^2 + L^2/4)} [/tex]

I don't know how to proceed further
