Both the comb and the hair become electrostatically charged.
This charging process occurs due to the \text{\_______________________} between the plastic comb and the hair.
The plastic comb gains a net negative charge, which leaves the hair \text{\_______________________} charged.
If the negatively charged comb is brought near another negatively charged plastic object, they will \text{\_______________________} each other.
This electrostatic charging is caused by \text{\_______________________} transferring from the hair to the comb.
