An isolated conducting spherical shell with a negative charge will experience charge redistribution when a positively charged metal object is placed in contact with its interior. The discussion explores three scenarios based on the magnitude of the positive charge relative to the negative charge. When the two conductors touch, charges can freely pass between them, leading to a net charge that will ultimately reside on the outer surface of the spherical shell. The movement of charges occurs because positive charges, which are essentially a deficit of electrons, can be neutralized by the migration of electrons from adjacent neutral atoms. This process results in the redistribution of charge, confirming that the net charge will be on the outer surface of the shell rather than the interior conductor.
