Homework Answers
a) Since Q3= -3Q , This charge is the result of induction of charge +3Q on the inner surface. Thus Q2= +3Q.
Now Q2= +3Q again is the result of induction of charge -3Q on the solid sphere.
Thus Q1= -3Q
b) Though the shell has negative charge on outer surface and positive charge on inner surface, it’s actually neutral. So when a metal wire is connected half of the charge will withdrawn from the solid sphere and get into the shell. Thus both have equal charge = Q’= -3Q/2 = -1.5Q
