A long, straight wire is surrounded by a hollow metal cylinder whose axis coincides with that of the wire. The wire has a charge per unit length of à, and the cylinder has a net charge per unit length of 21. From this information, use Gauss's law to find the following. (Assume the charge per unit length, à, is positive. Use any variable or symbol stated above along with the following as necessary: ɛo and r.) (a) the charge per unit length on the inner surface of the cylinder Ainner = (b) the charge per unit length on the outer surface of the cylinder Aouter= (c) the electric field outside the cylinder a distance r from the axis magnitude E = direction ---Select---
