2. A long thin wire carries a uniform linear charge density. This wire is sur- rounded by a long thin cylindrical shell, coaxial with the wire, of radius R and surface charge density o. Use Gauss's law to calculate the net electric field a distance 8 away from the wire (where 8 2 R) and determine the wire's charge density if the field vanishes everywhere outside of the shell.
