Question

when a negatively charged object brought close to positively charged electroscope does the divergence of its leaves decrease or increase?​

Answer 1

When the positively charged body is brought near to the disc of a positively charged gold leaf electroscope, the divergence between the gold leaves increases as like charges repel each other.

Therefore, when a negatively charged object brought close to positively charged electroscope the divergence of its leaves decreases as unlike charges attract each other.
