Two long, charged, thin-walled, concentric cylindrical shells have radii of 3.4 and 7.7 cm. The charge per unit length is 5.9×10−6 C/m on the inner shell and −10.7×10−6 C/m on the outer shell. What are the (a) magnitude E and (b) direction (radially inward or outward) of the electric field at radial distance r = 4.9 cm? What are (c) E and (d) the direction at r = 11 cm ? (a) Number Units (b) (c) Number Units (d)
