Question

A.
It stays uncharged.

B.
It becomes positively charged.

C.
It becomes negatively charged.

D.
It loses electrons.

Answer 1

When a comb becomes positively charged, it does so because it has lost electrons. The electrons have moved from the comb to the hair, causing the hair to gain those electrons. As a result, the hair becomes negatively charged.

Therefore, the correct answer is:

C. It becomes negatively charged.
