An ebonite rod is rubbed with fur. The fur is brought near a positively charged gold leaf electroscope. What will be your observation? Give reason.
Observation: Divergence of leaves increases.
Reason: When an ebonite rod is rubbed with fur, the ebonite rod is charged negatively and the fur is charged positively. When the positively charged fur is brought near the disc of a positively charged gold leaf electroscope, the electrons move from the leaves to the disc, so the positive charge on the leaves of the electroscope increases due to which the divergence of leaves increases.
