(8) [5 points] A charged rod has length 2L and constant linear charge density A. (a) what is the vector direction of the electric field at point P, a distance d above the rod. (b) Derive the magnitude of the electric field at point P. Divide the rod into infinitesimal segments and nd the electric field produced by one segment. Identify which components cancel and which will not. (c) Show that the field at P when d >> L is lcQ/d2 as expected. (d) Also find the field at P when (1
