Question

Does comb gets positively charged or negatively charged after combing hair? Does it lose valency electrons or free electrons after rubbing?​

Answer 1

Answer:

When hair is combed then the unwanted electrons from the hair go into the comb and hair acquires a positive charge. Now both hair and comb attract each other. After combing the comb becomes negatively charged because each material has a tendency to lose or gain electrons
