A Faraday's experiment was conducted following the steps below, using the structure shown in the figure. (i) A sphere with charge Q is carefully inserted into an insulated metal box without touching the walls. (ii) The exterior of the metal box is momentarily grounded and then disconnected from the ground, returning the metal box to an insulated state. (iii) The charged ball, carefully inserted so as not to touch the metal box, is removed. (a) Draw the distribution of charges inside and outside  (b) Calculate the net charge of the metal box after the charged ball has been removed.
