Answer 1

Answer:

When the positively charged 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.

In this case, when the charged body is brought near the positively charged electroscope the electrons from gold leaves shifts due to induction. Therefore, the amount of positive charge on gold leaves in creases and the divergence increases.

Hence option A is correct answer.
