28. (a) In Eq. 23-12, λ = q / L where q is the net charge enclosed by a cylindrical Gaussian surface of radius r . The field is being measured outside the system (the charged rod coaxial with the neutral cylinder) so that the net enclosed charge is only that which is on the rod. Consequently, 9 2 00 2.0 10 2.4 10 N/C. 2 2 (0.15) E r επ ε λ× == = × π G (b) Since the field is zero inside the conductor (in an electrostatic configuration), then there resides on the inner surface charge
