Question

What does the law of conservation of electric charges state?
$\left( a \right)$ The sum of the total electrons in any system is a constant quantity.
$\left( b \right)$ The sum of total neutrons in any system is a constant quantity
$\left( c \right)$ The sum of the total protons in any system is a constant quantity
$\left( d \right)$ None.

Answer 1

Hint: For answering this question we need to know about the charge and as we know that the charge is a property which gets connected with the matter due to which it produces some effects which can be magnetic and electrical. So by knowing this and taking the statement into consideration we can choose the correct option.

Complete Step by Step Solution: The conservation of electric charges states that the net charge of an isolated system will always remain constant.
The charge can be created and destroyed, but only in positive-negative pairs.
Therefore, both $\left( a \right)$ and $\left( c \right)$ have to be the right answers.

Additional information: Electric charge is the physical property of matter that causes it to come under a force when placed in an electromagnetic field. There are two types of charges, positive and negative.
Like charges repel and unlike charges attract each other. Something that has no charge can be called a neutral. Electric charge is carried by both protons and electrons.
If, in the nuclei of atoms, the number of electrons is higher than protons, then, it will have a negative charge. In an alternative case, where the number of electrons is less than that of protons, then, it will have a positive charge. If electrons and protons are equal in number then, it will be neutral.
The charge of an electron is –e and that of a proton is +e
The standard unit for a charge is Coulomb. Charges are additive in nature.
Electrical conduction is the movement of electrically charged particles through a medium. The movement can form an electric current in response to an electric field.

Note: Sometimes there can be multiple correct answers for a single question, so we must carefully understand each option and answer. We should also know that the net charges will be the neutral which means that there will be the same number of protons and electrons. And for each of the protons there will be the electron which will balance it.
