2. The electric field outside Y is zero.
3. The charge density on both spheres isthe same.

1. I only
2. III only

8）A small positively charged sphere is lowered by a nonconducting thread into a grounded metal cup without touching the inside surface of the cup, as shown above. The grounding wire attached to the outside surface is disconnected and the charged sphere is then removed from the cup. Which of the following best describes the subsequent distribution of excess charge on the surface of the cup?a

1. Negative charge resides on the inside surface, and no charge resides on the outside surface.
2. Negative charge resides on the outside surface, and no charge resides on the inside surface.
3. Positive charge resides on the inside surface, and no charge resides on the outside surface.
4. Positive charge resides on the outside surface, and no charge resides on the inside surface.
5. Negative charge resides on the inside surface, and positive charge resides on the outside surface.

34?)Which of the following statements contradicts one of Maxwell’s equations?

1. A changing magnetic field produces an electric field.
2. A changing electric field produces a magnetic field.
3. The net magnetic flux through a closed surface depends on the current inside.
4. The net electric flux through a closed surface depends on the charge inside.
5. The electric field due to an isolated stationary point charge is inversely proportional to the square of the distance from the charge.v
