Question

A positively charged rod is touched with the brass disc of a positively charged gold leaf electroscope. What is the effect on divergence of leaves?

• A. divergence decreases
• B. divergence increases
• C. divergence remains unaffected
• D. the leaves completely collapse

Answer 1

The correct option is B

divergence increases

When a positively charged rod is touched with the brass disc of a positively charged gold leaf electroscope, the divergence of leaves increases as the electrons move from the leaves to the positively charged rod through the brass disc of electroscope with the result that positive charge on leaves increases.
