WebAug 29, 2015 · For a point that is a distance z from a line extending from x = − a to x = b, with a charge density λ per unit length, the field is. E z = λ 4 π ϵ 0 z ( b z 2 + b 2 + a z 2 + a 2) It follows that when the source is not centered, the field due to the more distant line source will be weaker ( z is greater). In the limit where the line is ... WebThe electric field line patterns for other charge configurations are shown in the diagrams below. In each of the above diagrams, the individual source charges in the configuration …
