Question

When a glass rod is rubbed with a silk cloth, charges appear on both. A similar phenomenon is observed with many other pairs of bodies. Explain how this observation is consistent with the law of conservation of charge.

Answer 1

When a glass rod is rubbed with a silk cloth, opposite charges appear on both, because electrons are transferred from glass to silk. In this process, charge is not created or destroyed. It is merely transferred from one body to another. Hence, this observation is consistent with the law of conservation of charge.
