Charging an object by friction does not violate charge conservation because the charge is:
ATransferred, not created
BCreated from nothing
CDestroyed on contact
DConverted into heat
Answer & Solution
Correct answer: A. Transferred, not created
1. Conservation constrains what rubbing two objects can do.
2. Rubbing can leave one object positively charged.
3. This universally obeyed law of nature is called the law of conservation of charge.
4. Neutral objects contain equal quantities of positive and negative charge.
5. So the charge is transferred between the objects rather than created.
