Expert Answer:

The electric field inside a conductor is zero. So, if the conductor has a cavity and then you place a charge inside the cavity, then the internal surface of the conductor will acquire a charge with magnitude equivalent to that of the charge placed inside the cavity but of opposite sign. This will happen to ensure that all electric field lines which will originate from charge placed inside conductor will finish within the conductor itself. 
 
The charge distribution on the conductor surface takes place in a manner such that the net charge inside the conductor would be 0.
