# Does paper have a positive or negative charge?

## Does paper have a positive or negative charge?

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.

What happens when you bring the rubbed comb near the bits 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. When the comb is brought close to paper an opposite charge is induced in the paper, and the opposite charges attract.

### What would be the result of rubbing paper with fur?

As a consequence of rubbing the rod with the fur, the rod gains mass and the fur loses mass. the electric force between charged particles decreases with increasing distance.

Why do combs get charged?

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.

#### What is the charge on the comb?

The comb, covered in negatively charged electrons, becomes negatively charged as well, and your hair is left with a positive charge. This “separation of charge” is the reason for the collection of effects we call static electricity. If two objects have different charges, they attract (or pull towards) each other.

How do you find electrostatic charge?

Static electricity can be created by rubbing one object against another object. This is because the rubbing releases negative charges, called electrons, which can build up on one object to produce a static charge.

## What happens when two materials are rubbed together?

Likewise, when two materials that tend to attract electrons are rubbed together, the one with the greatest tendency will moderately become negative (−) in charge. Rubbing a glass rod with a silk cloth will charge the glass with positive charges. The silk does not retain any charges for long.

What happens when you rub fur and wool together?

Although the rod can be used to pick up scraps of paper, the fur and wool quickly lose their charge. Moderate combinations. When two materials that tend to give up electrons are rubbed together, the one with the greatest tendency will moderately become positive (+) in charge.

### What happens when a glass rod is rubbed with silk cloth?

So after rubbing, the glass rod becomes positively charged and the silk gets negative charge. So glass acquires a greater order than silk as electron losses. Therefore, on rubbing, glass gets a positive charge and silk gets a negative charge. On both of them, equal but opposite charges are produced.

What happens when you rub a straw on paper?

Apparently, after the straw has been rubbed there is an interaction between the straw and paper which is capable of lifting the scraps of paper. What can you say about the size of this interaction compared to that of the earth’s gravitational interaction with the scraps of paper?
