Two conducting spheres are far apart. The smaller sphere of
radius R carries a total charge Q. The larger sphere is neutral and
has a radius r where r =2.4 R. After the two spheres are
connected by a conducting wire, the charges on the larger and
smaller, respectively, are:
Q/2 and Q/2
0.29 Q and 0.71 Q
Q and zero
0.71 Q and 0.29 Q
Q and 2Q
