Hi thank you for asking the question
when plastic comb is rubbed against dry hair electrostatic forces are produced
Electrostatic forces are non-contact forces; they pull or push on objects without touching them.Rubbing some materials together can result in something called ‘charge’ being moved from one surface to the other.Charged objects pull on other uncharged objects and may either push or pull on other charged objects.There are two sorts of charge; scientists do not know exactly what charge is or how the two sorts of charge differ; they call the two sorts ‘positive’ and ‘negative’.Lightning is the result of rapid charge movements in storm clouds.

Hey...
This is because the comb gets charged when it is rubbed. This charge that is created when two objects are rubbed against each other is called static electricity.

When the comb is brought near neutral paper strips. Within the papers strips, the electrons get either repelled or attracted according to whether the comb has a negative or a positive charge. This makes the paper strips have an unlike charge in the direction of the comb, and makes them rise towards it.
Hope this would help you.
Mark it as brainliest if you like.
