Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. Which statement best describes the Law of Conservation of Charge?
Charge can be created or destroyed, but not transferred.
The total electric charge in an isolated system remains constant.
Electrons are always positive.
Protons can move freely between atoms.
2. If a neutral object gains 5 electrons, what is its net charge?
+5e
-5e
0
Depends on the material
3. The fundamental unit of charge is the , carried by a single electron or proton.
4. When two objects are rubbed together, electrons are from one object to the other, resulting in both objects becoming charged.
5. In an isolated system, the algebraic sum of all electric charges remains .
6. The Law of Conservation of Charge only applies to conductors.
True
False
7. Charging by induction involves direct contact between charged and uncharged objects.
True
False
8. Explain how rubbing a balloon on your hair demonstrates the conservation of charge.
9. Consider the simple electric circuit shown below. If the current flowing out of the battery is 2 Amperes and it splits into two paths, with 0.8 Amperes flowing through the first path, what is the current flowing through the second path, according to the conservation of charge?
