Homework Statement
We have a line charge of density λ and length 2L along the x axis. What is the electric field at the point (0,1,1)m for L=1cm and λ=200μC/m? (Hint: no new integral is required.)
Homework Equations
E=(kq)r^2
The Attempt at a Solution
I drew a figure and noticed that the equation for E should be multiplied by 2 since the charged line at both sides of the x-axis are affecting the point. I think I remember how to do this in 2D, but for some reason 3D is confusing me. Thanks in advance.
