Homework Statement
[/B]
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 smaller and larger spheres, respectively, are:
A. Q/2 and Q/2
B. Q/3 and 2Q/3
C. 2Q/3 and Q/3
D. zero and Q
E. 2Q and −Q
The Attempt at a Solution
[/B]
I thought that charge would spread equally by the two spheres, but it seems that it deppends on the radius of them. Can someone tell me why? mathematically if possible. Also, why does the potential does NOT deppend on the radius? since we have V = Qk/r
