Question

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

Answer 1

The correct option is A Divergence increases

When the positively charged rod is touched on the disc of a positively charged gold leaf electroscope, the divergence between the gold leaves increases as like charges repel each other.
Hence, the divergence increases as the positively charged rod is rolled on the disc of the positively charged gold leaf electroscope.
