What is the process by which an electrically charged object imparts a charge to another object?

• A. Electric induction
• B. Electric conduction
• C. Electric discharge
• D. Coulomb's interaction

Answer: (A)

The correct answer is electric induction, which refers to the process where a charged object influences the charge distribution within a nearby neutral object without direct contact. When an electrically charged object is brought near a neutral conductor, it causes the electrons within the conductor to rearrange themselves. This results in one side of the conductor being negatively charged and the other side being positively charged, creating a separation of charges. If the conductor is then grounded or otherwise allowed to lose or gain electrons, it can acquire a net charge that mirrors that of the charged object.

This phenomenon is critical in understanding electrostatic principles and various applications involving capacitors and electrostatic fields. In contrast, electric conduction involves the direct movement of charge carriers (such as electrons) through a material, which is not the method through which one object imparts a charge to another. Electric discharge refers to the release of accumulated electric charge, often seen as a spark or lightning, while Coulomb's interaction describes the fundamental force between charged particles, rather than a process of charge induction.
