Hi! Thank you for your help~
I am working on a problem about electric fields. There is a rod along the x axis from -3m to 3m with a lambda linear density of 12 x10^-9 c/m. I am supposed to find the electric field on the y axis at y = 0.2m .
If you could tell me what process, what variables and integration I have to use, that would be really great. Thank you very much.
I know that I have to use both calculus and trigonometry, but Im not sure how to go about the problem.
I know that E= (kq/(r^2)) and that this equals k(integral[dq / r^2)) and I know that the y component of distance between the 0.2m mark on the y axis and the rod (which is massless) is varying depending upon where along the rod you look.
