Question

When an ebonite rod is rubbed with the cat skin, compare the magnitude of charges acquired by them, and state the nature of charges on them.

Answer 1

1. When two substances are rubbed together, few electrons are transferred from one material to another.
2. For example, an ebonite rod is rubbed with the fur, the ebonite rod pulls some electrons from the fur, as electrons are loosely packed in the fur as compared to the ebonite rod.
3. Therefore, the ebonite rod becomes negatively charged and the fur becomes equally positively charged.
