Knowledge Check

  • Assertion: Two electrically neutral metal spheres in contact are moved closer to a charged object and then separated away from each other using insulating handles in the presence of e charged object, Both the neutral objects acquire equal and opposite charges. Reason: When two metallic objects in contact are brought closer to a charged object then electrons are transferred from one object to the other due to induction phenomenon. If we separate the objects in presence of a charged object then electrons are unable to flow back to the original object.
