This is due to a line of charge that rests on an axis and evaluating the electric field at a point that is also on the same axis. Will the radius, no matter what always be positive?
So if one end of a uniform line of charge is placed at the origin that extends in the negative x-axis and there is some point at -b (that is not on the line of charge) that I am to evaluate the electric field, would my radius be r=(x-b) in the integrand?
