Question

When combing one's hair, the comb becomes positively charged. What happens to the hair being combed?
A.
It loses electrons.


B.
It stays uncharged.


C.
It becomes positively charged.


D.
It becomes negatively charged.

Answer 1

When a comb becomes positively charged, it means that it has lost some electrons. Since like charges repel and opposite charges attract, the hair, which originally is neutral, will have electrons attracted to the positively charged comb. As a result, the hair will gain electrons and become negatively charged.

Thus, the correct answer is:

**D. It becomes negatively charged.**
