You are provided with a negatively charged gold leaf electroscope. State and explain what happens when an ebonite rod rubbed with fur is brought near the disc of electroscope?

The correct option is D. divergence increases
On rubbing an ebonite rod with fur, the electrons from the fur get transferred to the ebonite rod. The fur now has a deficiency of electrons and so is positively charged. On the other hand, the ebonite rod has an excess of electrons and hence is negatively charged.
In the above case, the fur undergoes positive electrification.
Now, when the negatively charged ebonite rod is touched on the disc of a negatively charged gold leaf electroscope, the divergence between the gold leaves increases as like charges repel each other.
Hence, the divergence increases when an ebonite rod rubbed with fur is brought near the disc of the negatively charged electroscope.
