Neutral Conducting Charged Hollow Cylinder Conducting Wire E, -2a 3a b C A very long charged conducting wire, of radius a = 6.00 cm, is enclosed by a concentric, conducting neutral hollow cylinder, as shown in the diagram above. The electric field is E1 = 1.90x104 N/C at b = 9.00 cm from the center of the wire and in the direction shown. What is the magnitude of the electric field at point P, a distance of c= 21.0 cm from the center of the wire? Magnitude
