Problem

A solid plastic sphere initially carries a uniform positive charge density throughout its volume. A small, completely empty spherical cavity is drilled out of the interior without removing any charge from the remaining material. Qualitatively describe the electric field that now exists inside the cavity and state the reason for its presence.
