## Why does rubber attract paper?

The fibers have lost electrons giving them a positive charge. The rubber gained electrons giving it a negative charge. The positively charged fibers are now attracted to the negatively charged balloon. The negatively charged balloon attracts the paper.

## Is paper positively or negatively charged?

The bits of paper are electrically neutral, but when you bring the rod close to them, even though paper is not a conductor, that is, the charges within it are not free to move about as a current, the negative charges have enough mobility that they are repelled by the rod.

## Why is paper attracted to a charged rod?

A positively charged rod is brought near a piece of paper. … When the positively charged rod is brought near the neutral paper, it induces a negative charge on the side of the paper nearer to the rod. Since unlike charges attract each other, the paper will be attracted to the rod.

## How does a comb attract paper?

You can observe static electricity if you run a plastic comb through your hair, then place the comb near small pieces of paper. The paper is attracted to the comb. This happens because the charged comb induces an opposite charge in the paper and as opposite charges attract, the paper sticks to the comb.

## Is there any interaction between the paper and plastic cover?

When it comes near the neutral paper, the negative tape pushes on the negative charges in the paper and pulls on the positive charge. … This charged air could then be repelled by the parts of the plastic with the same charge and attracted to the opposite charge plastic.

## What happens when you rub a plastic comb on your hair?

If you comb your hair, for example, electrons leave the atoms and molecules in your hair and travel to the plastic comb. The comb, covered in negatively charged electrons, becomes negatively charged as well, and your hair is left with a positive charge.

## Why do neutral objects not attract each other?

So a neutral sphere will not polarize unless a net charge pushes/pulls the negatives to one side and the positives to another. But a neutral object does not have a net charge, so it cannot separate the charges in another neutral object.

## Do 2 neutral objects repel?

When an atom has an equal number of protons and electrons, the charges cancel each other and the atom is said to be neutral. … Objects with like charges repel each other, while those with opposite charges attract each other.

## What happens when you rub two insulators together?

When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be ‘rubbed off’ one material and on to the other. The material that gains electrons becomes negatively charged. The material that loses electrons is left with a positive charge.
