Homework Statement
Two thin rods of length L lie on the x axis. One of them has a charge of
-Q uniformly distributed along its length and is positioned between x = -L
and x = 0. The other one has a charge of +Q uniformly distributed along
its length and is positioned between x = 0 and x = L. Find the electric field
produced by the two rods (magnitude and direction) at a point O located on
the y-axis at y = h.
Homework Equations
I would imagine the relevant equation is E=kq/r^2.
I would kind of like to solve this without calculus, since i don't understand that.
The Attempt at a Solution
I think the vertical components cancel out. After that, I really have no idea what to do. Maybe you plug in the distance into the above formula. I am really confused with this problem.
