Suppose You Electrically Charge a Transparency by Rubbing It, and Then

question 20

Multiple Choice

Suppose you electrically charge a transparency by rubbing it, and then hang the transparency, at rest, by a string in the center of a room. Except for the transparency and string, the room is totally evacuated of all matter. Neglecting any influences from outside the room, what kinds of fields would then be found at places inside the room but away from the transparency-- for instance, at a point near a corner of the room?

• A) a magnetic field only
• B) an electric field only
• C) Both an electric and magnetic field
• D) No fields at all, because the transparency would create electromagnetic fields only within the transparency itself
• E) No fields at all, because there is nothing [no material object] at such a point
