Question

-) If a glass rod rubbed with silk is brought
near the cap of a negatively charged
electroscope, the divergence of leaves will
decrease.​

Answer 1

Answer

Because when the positively charged glass rod is touched on the disc of a negatively charged gold leaf electroscope, the electrons shifts towards rod, hence amount of charge on gold leaves decreases and the divergence between the gold leaves decreases as unlike charges attract each other.
