1. The problem statement, all variables and given/known data Given an infinitely long line of charge density λ extended along the x-axis, what is the electric field at a point X = x(x')+y(y')+z(z') (in space)? 2. Relevant equations E = kq / r^2, dq = (lamda)dx 3. The attempt at a solution dE = kλ ∫ [x(x')+y(y')+z(z')- x(x')] dx / [(y^2) +(z^2)]^(3/2) (integral from -∞ to +∞) I end up getting 0 because -∞ + ∞ equals 0?
