A charged wire of negligible thickness has length 2L units and has a linear charge density lambda. Consider the electric field E rightarrow at the point P, a distance of above the midpoint of the wire. The field E rightarrow points along one of the primary axes. Which one? i^j^k^What is the magnitude E of the electric field at point P? Throughout the part, express your answers in terms of the constant k, defined by k = 1/4 pi. E =
