The charge enclosed the cavity has not changed. Hence, the flux will not change.
A spherical cavity is hollowed out of the interior of a neutral conducting sphere. At the center of the cavity is a point charge, of positive charge q.
Now a second charge, q2, is brought near the outside of the conductor. Which of the following quantities would change?
(a) The electric cavity within the cavity, Ecav.
(b) The electric field outside the conductor, Eext.
