A line charge with charge density = +35 C/m lies along the central axis of a thin, charged cylindrical shell with radius R = 17 cm. At a distance r = 45 cm from the central axis, the electric field is measured to be E = 3.9 105 N/C in a direction that is outward and perpendicular to the central axis. What is surface charge density of the cylindrical shell? For the limit check, investigate what happens to if the electric field at the same spot becomes extremely weak (i.e., E 0)
