When two bodies are rubbed against each other, several things can happen. One of the most common phenomena observed is the transfer of electric charges between the bodies. This process is known as charging by friction or triboelectric charging.
Charging by friction:
When two bodies are rubbed against each other, the outermost electrons of one body can be transferred to the other body. The body that loses electrons becomes positively charged, while the body that gains electrons becomes negatively charged. This transfer of electrons results in the bodies acquiring equal and opposite charges.
The Law of Conservation of Charge:
The Law of Conservation of Charge states that the total charge of an isolated system remains constant. In other words, charge can neither be created nor destroyed. Therefore, the total charge of the two bodies before and after rubbing will remain the same. However, the distribution of charges between the bodies will change.
Equal and opposite charges:
Based on the Law of Conservation of Charge, we can conclude that when two bodies are rubbed against each other, they acquire equal and opposite charges. This means that if one body gains a certain amount of negative charge, the other body will acquire an equal amount of positive charge.
Example:
For example, when a plastic comb is rubbed against dry hair, the comb becomes negatively charged due to the transfer of electrons from the hair to the comb. At the same time, the hair becomes positively charged. The charges acquired by the comb and the hair are equal in magnitude but opposite in sign.
Conclusion:
In conclusion, when two bodies are rubbed against each other, they acquire equal and opposite charges. This phenomenon is a result of the transfer of electrons between the bodies. Charging by friction is a fundamental concept in the study of electricity and has various applications in everyday life, such as in the functioning of Van de Graaff generators and static electricity experiments.
