A line of charge with uniform density extends between z = -L/2 and z = L/2 along the z-axis. Apply Coulomb’s law to obtain an expression for the electric field at any point P (r, 0) on the x–y plane. Show that your result reduces to the expression given by Eq. (4.33) as the length L is extended to infinity.
