- 27. Properties of ElectricCharges (Summery) Electric charges have the following important properties: Charges of opposite sign attract one another, and charges of the same sign repel one another. The total charge in an isolated system is conserved. Charge is quantized.
- 28. Properties of ElectricCharges An object carries a charge of -8.0 µC, while another carries a charge of -2.0 µC. How many electrons must be transferred from the first object to the second so that both objects have the same charge?
- 29. Properties of ElectricCharges A metal sphere has a charge of +8.0 µC. What is the net charge after 6.0×1013 electrons have been placed on it?
