Read each question carefully and provide your best answer. Show all your work for calculation problems.
1. Which of the following statements best describes the principle of conservation of charge?
Charge can be created or destroyed, but only in pairs.
The total electric charge in an isolated system remains constant.
Positive charges are always conserved, but negative charges are not.
Charge is quantized, meaning it only exists in discrete units.
2. When a glass rod is rubbed with silk, the rod acquires a positive charge. What happens to the silk?
It acquires an equal positive charge.
It remains neutral.
It acquires an equal negative charge.
It acquires a smaller negative charge.
3. The total electric charge in an isolated system is always .
4. Charge is transferred, not created or destroyed, during the process of .
5. The conservation of charge means that the number of electrons and protons must always be equal in any given system.
True
False
6. When a charged object touches an uncharged object, charge can be transferred, but the total charge of the two objects combined remains the same.
True
False
7. Explain what an 'isolated system' means in the context of the conservation of charge.
8. A neutral object is charged by induction. Does this process violate the law of conservation of charge? Explain why or why not.
9. Two identical conducting spheres, one with a charge of +6 µC and the other with a charge of -2 µC, are brought into contact and then separated. What is the final charge on each sphere?
10. A lightning bolt carries approximately 15 C of charge. If this charge is transferred from a cloud to the ground, what can be said about the total charge of the cloud-ground system before and after the lightning strike?
