Solution:
A body is brought near to a negatively charged gold leaf electroscope. If the divergence of leaves increases. The nature of charge on the body is negative.When the negatively charged rod is brought near to a negatively charged gold leaf electroscope, the divergence between the gold leaves increases as like charges repel each other. In this case, the divergence increases as the charged body is brought near to the negatively charged gold leaf electroscope, hence the charge is negative.
