Answer:
When two combs made of the same material are rubbed against hair, they acquire the same nature of charge. So, when they are brought near, they repel each other.
Answer:
when two charged body are oppositely charged then they attract but when two bodies have same charge then they repel
full explanation:-
Each body has atoms. An atom is electrically neutral. It has protons (positively charged) and neutrons (uncharged) inside ire nucleus at the centre, around which the electrons (negatively charged) revolve in different orbits. The number of electrons in an atom is equal to the number of protons. However, some of these electrons can easily leave their atoms. These are called free electrons. The two objects which are rubbed together are initially neutral (or uncharged). When they are rubbed together, the free electrons are transferred from one object to the other. The object which gains free electrons, becomes negatively charged, while the object which loses free electrons, becomes positively charged.
When an ebonite rod is rubbed with fur, the free electrons from the fur aretransferred to the ebonite rod. The fur loses some electrons and it becomes positively charged and the ebonite rod gains the same number of electrons and it becomes negatively charged by the same amount. The charges of ebonite rod and fur on rubbing .
