Which term describes the process by which a charged object can influence another object without direct contact?

• A. Static Electricity
• B. Charging by Friction
• C. Charging by Conduction
• D. Charging by Induction

Answer: (D)

The main idea here is how a charged object can influence another object without touching it. That non-contact influence happens through the electric field that the charged object creates. When a charged object is nearby, its field causes charges inside a nearby neutral object to rearrange: opposite charges collect on the side closest to the external charge, and like charges are pushed away. This redistribution occurs without any net transfer of charge between the objects, unless you provide a path to ground. This process is called charging by induction. It relies on the electric field to move charges within the second object, not on physically moving electrons from one object to another. That’s why induction is the term that best describes the situation of influencing a second object without direct contact. In contrast, static electricity is a general notion of stationary charges and their effects, not a specific method of charging. Charging by friction involves rubbing two objects together and transferring charge through contact. Charging by conduction requires the objects to touch so charges move directly from one to the other.
