Question
A positively charged rod is brought near the disc of a positively charged gold leafelectroscope. State your observation with reason
Solution
When a positively charged rod is brought near the disc of a positively charged gold leaf electroscope, the gold leaves will repel each other more strongly and diverge further apart.
This is because like charges repel each other according to Coulomb's law. The positively charged rod strengthens the existing positive charge on the electroscope, causing the gold leaves (which are also positively charged) to repel each other more strongly. This increased repulsion causes the leaves to spread further apart.
