Two conducting spheres are far apart. The smaller sphere carries a total charge Q. The larger sphere has a radius that is twice that of the smaller and is neutral. After the two spheres are connected by a conducting wire, the charges on the larger and smaller, respectively, are:

a) Q/2 and Q/2

b) Q/3 and 20/3

c) 20/3 and Q/3

d) zero and Q

e) Q and 20
