Concept:Rubbing a comb transfers electric charges and creates static electricity.
Explanation:When a plastic comb is rubbed through dry hair, friction between the comb and the hair causes electrons to move from one material to the other.
The hair loses electrons, so it becomes positively charged.
The comb gains electrons, so it becomes negatively charged.
This build-up of stationary charges is known as static electricity.
The charged comb then produces an electrostatic force, which allows it to attract neutral objects such as small bits of paper or loose hair strands.
Friction is only the process that causes the charge transfer, not the resulting force.
Answer:D. electrostatic force.
