    The sphere of a Van de Graaff generator has a charge of +3.28 μC. A small metal sphere nearby has a charge of +219 nC. They are separated 2.00 m. Let us set axes so that the origin is at the centre of the Van de Graaff generator and the small sphere is at 2.00ˆi m. They are far enough apart that we can make the approximation that they are not polarizing each other, so they can be treated as...
