Want this question answered?
when rubbed with hair, ruler acquires some charge due to static electricity...becomes charged body and attracts tiny pieces of paper towards it.
When refill is rubbed with plain did the paper pieces
Yes, it will because of the negative and positive charges which are on the objects, the rod will pick the small pieces of paper up.
Plastic is an insulator where as metal is a good conductor

Your ability to pick up anything (it is harder when your hands are greasy), your ability to walk (that is why it is more difficult on ice), why your hands feel warmer when they are rubbed together.

The plastic rod gains static electricity.
The reason why the pieces of paper are neutral is that they contain equal amount of positive and negative charges and so they cancel each other out. When you bring a charged plastic comb to the pieces of paper, the charge opposite to that of the plastic comb will be brought to a part of the surface of the paper where the plastic comb is. Opposite charges attract each other, and since you're holding the comb, the pieces of paper will be attracted to the comb.
The tip of a ball pen is plastic. When plastic is rubbed in a person's hair it attracts light objects due to static electricity. It can be any plastic that will create the static electricity. Even an inflated balloon will do this trick.
It indicates that both strips have either both positive or negative charges therefore the plastic strips repel each other.
the rod slightly attract each other
