Homework Statement
A line charge of uniform charge density Q' is distributed along a square contour a on a side. The medium is aie. Find the electric field intensity vector at a point that is at a distance a from each of the square vertices.
Homework Equations
The Attempt at a Solution
I've got everything figured out expect for the line integral which will give me the electric field vector for one of the sides of the square contour.
In the figure attached (my work), I've denoted this as, [itex]\vec{E_{1}}[/itex].
How do I write out this integral?
I know that the radius in the calculation of the electric field is going to vary from a to h then back to a as we move along one side of our square contour, but how do I represent this knowledge in an integral that will evaluate the changing r for infinitesimly small lengths (dl) along one side of the square contour?
