Which option describes Charge Separation by Polarization as a charging method?

• A. Charging by Friction
• B. Charging by Conduction
• C. Charging by Induction
• D. Charge Separation by Polarization

Answer: (D)

The main idea here is that polarization charges a neutral object by rearranging its internal charges in response to an external electric influence. When a neutral object is placed near a charged body or in an electric field, the internal charges shift slightly: negative charges are drawn toward the external positive region and pushed away from it, while positive charges shift in the opposite direction. This creates a separation of charge within the object—one side becomes relatively negative and the other relatively positive—without any net transfer of electrons into or out of the object. Because no net charge is added or removed, polarization describes the internal rearrangement that forms a dipole in the material. This is distinct from charging by friction or by conduction, which involve actual transfer of charge between bodies, and it’s a specific form of charging where the effect comes from induced separation of existing charges rather than transfer.
