How does charging by contact using a negatively charged rod and grounding result in producing same charge in a metal sphere?
Asked by Michelle | 8th Feb, 2012, 10:35: PM
Charging by conduction involves the contact of a charged object to a neutral object. Suppose that a positively charged aluminum plate is touched to a neutral metal sphere. The neutral metal sphere becomes charged as the result of being contacted by the charged aluminum plate. Or suppose that a negatively charged metal sphere is touched to the top plate of a neutral needle electroscope. The neutral electroscope becomes charged as the result of being contacted by the metal sphere. Each of these examples involves contact between a charged object and a neutral object.
