Question
A long straight cylindrical shell has an inner radius Riand an outer radius Ro. It carries a current i, uniformly distributed over its cross section. A wire is parallel to the cylinder axis, in the hollow region (r<Ri). The magnetic field is zero everywhere outside the shell (r>Ro). We conclude that the wire:A) is on the cylinder axis and carries current iin the same direction as the current in the shell
B) may be anywhere in the hollow region but must be carrying current iin the direction opposite to that of the current in the shell
C) may be anywhere in the hollow region but must be carrying current iin the same direction as the current in the shell
D) is on the cylinder axis and carries current iin the direction opposite to that of the current in the shell
E) does not carry any current
