Consider a long cylindrical shell of non-conducting material which carries a surface charge fixed in place (glued down) of `sigma C//m^(2)`, as shown in Figure. The cylinder is suspended in a manner such that it is free to revolve about its axis, without friction. Initially it is at rest, then it is spinned until the speed of the surface of the cylinder is `v_(0)`. What is magnetic field inside the cylinder?

A

`sigmav_(0)dx`

B

`mu_(0)sigmav_(0)`

C

0

D

none of these
