Answer 2

yeah,no charge will reside on the inner surface.that's the property of a conductor in electrostatics.if there is some charge on the inner surface,an electric field will be set up,forcing the charges to move and thus settting up a current.but under static conditions,charges are at rest.one can also see it using gauss's law.
