Question

A plastic comb is rubbed in a dry hair. Describe how you will use a gold leaf electroscope to determine the charge on the comb​

Answer 1

Answer:

After rubbing, the plastic comb acquires negative charge. When it is touched with the metal cap of an electroscope then both the metal cap and the leaves acquire negative charge due to conduction. Because of negative charge on both the leaves, divergence of leaves takes place.
