AP Physics 2
10.2 Conservation of Electric Charge and the Process of Charging
10.1 Electric Charge and Electric Force
An uncharged glass rod is rubbed against an uncharged silk cloth in an isolated environment. During the process, \(2.0 \times 10^{12}\) electrons are transferred from the glass rod to the silk cloth. Which row in the table correctly identifies the total net charge of the two-object system after rubbing and the final electric charge on the glass rod?
| Total Net Charge of System | Final Charge on Glass Rod | |
|---|---|---|
| Row A | \(+0.32\text{ }\mu\text{C}\) | \(+0.32\text{ }\mu\text{C}\) |
| Row B | \(0\text{ C}\) | \(+0.32\text{ }\mu\text{C}\) |
| Row C | \(0\text{ C}\) | \(-0.32\text{ }\mu\text{C}\) |
| Row D | \(-0.32\text{ }\mu\text{C}\) | \(-0.32\text{ }\mu\text{C}\) |
