A gold leaf electroscope is given a positive charge so that its leaves diverge.
A gold leaf electroscope is given a positive charge so that its leaves diverge. How is the divergence of leaves affected, when a positively charged rod is brought near its disc?
- A. Divergence increases
- B. Divergence decreases
- C. Divergence remains same
- D. can't say
Step-by-step solution
The electroscope is positively charged, causing its leaves to diverge due to repulsion. When a positively charged rod is brought near the disc, it repels positive charges from the disc toward the leaves. This increases the positive charge on the leaves, enhancing their repulsion and thus increasing the divergence.
