Work Step by Step
The net charge is still on the surface, because on a conductor, any excess charge always resides on the surface under electrostatic conditions (page 733).
This excess charge will not be uniformly distributed: more excess positive charge will be drawn to the side that is closer to the negative charge.
The surface charge distributes itself in such a way as to cancel the external electric field inside the conductor. Remarkably, the electric field everywhere inside the conductor is still zero.
