electroscopes are charged equal and opposite, then the charge is transferred
from one to the other. If tape is pulled off an electroscope plate, charge
will result and the tape will also charge a second electroscope with the
opposite charge. Picture. |
| 5A10.36 | equality of charges | E-14 | Rub a rubber
rod against a similar rod covered with wool in a Faraday ice pail. The electroscope
