A Van de Graaff generator includes a metal sphere of radius R=0.15m that is electrically isolated from its surroundings except for a wire which can carry current. When operational, the sphere has a potential of 400 kV. a) How much charge is on the sphere when it is fully charged? b) When the current is a steady I = 5.0 uA, how long does it take for the sphere to reach its operating potential if it is initially uncharged?

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...

Tthe Van de Graaff generator and sphere we have been assuming since the start that they are not polarizing each other. This is an approximation. In this question we will start to be able to assess how good this approximation is ? (a) Use the approximation that the Van de Graaff generator and ball are uniformly charged spheres to find the E-field very close to the surface of the Van de Graaff generator, at the point where the +ve x-axis...
