SUMMARY
When a conducting sphere rubs against metal, the interaction does not result in a fixed charge on the conducting sphere. This is due to the nature of metals acting as reservoirs of electrons, allowing for the easy flow of electrons in and out. The discussion emphasizes that the charge on the conducting sphere remains variable rather than fixed, challenging the notion of permanent charging through friction.
