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 skin of the cat, the ebonite rod pulls some electrons from the skin of the cat, as electrons are loosely packed in the skin of the cat as compared to the ebonite rod.
3. Therefore, the ebonite rod becomes negatively charged and the skin becomes equally positively charged.
