Question

Which statement is part of the principle of conservation of charge?

A Objects never run out of charge.
B When charges are destroyed, new charges are created.
C The total charge of any closed system is constant.
D Every object in the universe contains electrically charged particles.

Answer 1

It is D. An object can acquire a net charge only when charges are transferred to or from it.

Answer 2

Answer: Option C: The total charge of any closed system is constant.

Explanation: Suppose that we have an closed system in which we have a total amount of charge Q. Now, there is no proces in which the total charge can change, the only way in which we can do it is by extracting part of the charge or adding more charged particles, but we can not do this because the system is closed, this means that the total charge in a closed system must remain constant, and if we considerate the unvirese as a closed system we see that the total charge is conserved, so the correct answer is option C
