Question

objects may be charged in different ways. negatively charged rod positively charged rod positive charges in the object move toward the negative rod negative charges in the object move toward the positive rod what method of charging is shown in the above diagram? a. friction b. conduction c. convection d. induction

Explanation:

• Option A (friction): Friction charging involves rubbing objects to transfer charge. The diagram shows no rubbing, so A is incorrect.
• Option B (conduction): Conduction requires direct contact to transfer charge. The rods and object don’t touch, so B is incorrect.
• Option C (convection): Convection relates to heat transfer via fluid movement, not charging. Irrelevant here, so C is incorrect.
• Option D (induction): Induction charges by bringing a charged object near (no contact), causing charge separation in the object (positive charges move toward negative rod, negative toward positive rod). This matches the diagram, so D is correct.

Answer:

D. induction
