Question

Explain the law of charge conservation.

Answer 1

Hint: In order to solve this question, we are going to first give a definition for the law of conservation of energy, then we are going to explain the statement of the law more and also by giving the examples and the importance of this law of conservation of momentum.

Complete step by step solution:
The law of conservation of charge states that” charge can neither be created nor be destroyed but can be transferred from one system to the other.”
In other words, according to the law, in an isolated system, during any interaction, the charge cannot vary and the total charge remains constant. This means that any system that is not exchanging mass or energy with its surroundings will never have a different total charge at any two times.
The law of conservation of charge can be explained using two examples:
Due to friction, the two bodies that are rubbing against each other, gain two equal and opposite charges, and the total charge remains constant that is equal to zero.
Now during a radioactive decay, the proton splits into two particles, positron and a neutron both having charges such that the net charge is equal to zero.
The concept of conservation of momentum is important for all nuclear reactions, alpha decay, beta decay, etc.

Note: It is important to note that the charged particles can be created or destroyed as long as the net charge on the particles before and after the process remains the same. But in that case also, charge is not being created but the charged particles only transfer charge from one system to another.
