A thin rod of length ℓ and uniform charge per unit length λ lies along the x axis as shown in Figure P23.8. (a) Show that the electric field at P, a distance d from the rod along its perpendicular bisector, has no x component and is given by E = 2kλ sin θ0/d. (b) What If? Using your result to part (a), show that the field of a rod of infinite length is E = 2kλ/d.
