Unformatted text preview: o conducting spheres, one having three times the diameter of the other (labelled 1 and 3), are separated by a distance that is very large compared to their diameters. Initially, the smaller sphere (1) is uncharged and the larger sphere (3) has charge Q. How much charge must we remove from sphere (3) and add to sphere (1) in order to guarantee that both spheres have the same potential at their surface (relative to a potential of zero an infinite distance away)? 3 A) B) C) D) E) 1 Q/9 Q Q/16 Q/2 Q/4 Version 1 Page 3 5.
