## What happens when you rub a rubber rod with wool?

When the hard rubber rod is rubbed with wool, it gains electrons from the wool, gaining a negative charge.

## When a rubber rod is rubbed with fur the rod becomes negatively charged due to the transfer of?

Electricity and Magnetism Test

A B
How is a positive charge usually given to a neutral object? electrons are removed from the object.
When a rubber rod is rubbed with fur, the rod becomes negatively charged due to the transfer of electrons to the rod

## What happens when a rubber rod is rubbed with a piece of fur giving the fur a negative charge?

When a rubber rod is rubbed with a piece of fur, some of the electrons are transferred from the fur to the rubber rod. The rubber rod acquires a negative charge and the fur a positive charge.

## When a hard rubber rod is given a negative charge?

what will be the charge transfered ? Answer: When a hard rubber rod is given a negative charge by rubbing it with wool, negative charges are transferred from wool to rod.

## How do you make an uncharged object have a positive charge?

Question: To Make An Uncharged Object Have A Positive Charge? 1. Remove Some Neutrons2. Add Some Neutrons3. Add Some Electrons4. Remove Some Electrons

1. remove some neutrons.
4. remove some electrons.

## What is the charge on a glass rod rubbed with silk?

When the glass rod is rubbed with silk clothes, glass quickly loses electrons, and silk takes electrons out of the glass rod. So after rubbing, the glass rod becomes positively charged and the silk gets negative charge.

## What happens between a plastic rod rubbed with a piece of animal fur and a glass rod rubbed with a piece of silk when they are brought close to each other?

What happens between a plastic rod rubbed with a piece of animal fur and a glass rod rubbed with a piece of silk when they are brought close to each other? They attract each other.

## What objects are attracted to a plastic rod rubbed with wool?

Plastic rods rubbed with wool repel each other. Glass rod rubbed with silk attracts plastic rod rubbed with wool.

## What happens when two glass rod is rubbed with silk?

A glass rod becomes positively charged when rubbed with silk, while the silk becomes negatively charged. (a) The glass rod is attracted to the silk because their charges are opposite.

## What happens when you bring a glass bottle rubbed with silk near a plastic bottle rubbed with wool that is laying on its side?

You might know that all matter is made up out of atoms. When you are rubbing the glass rod with the silk cloth, electrons are stripped away from the atoms in the glass and transferred to the silk cloth. This leaves the glass rod with more positive than negative charge, so you get a net positive charge.

## What happens when an Ebonite rod is rubbed with silk?

When an ebonite rod rubbed with fur it acquires negative charge and when glass rod is rubbed with silk cloth it acquires positive charge. Therefore, they will attract.

## Why is it better to rub an Ebonite rod with fur rather than silk?

When you rub fur with ebonite rod, the chemical bond is formed between some parts of the the two surface. Rod has its electron more tightly bound than fur. So, fur donates electrons to the rod while electrons from rod wonâ€™t come out.

## What happens when amber is rubbed with silk?

When amber is rubbed with wool or silk, amber becomes positively charged. (b) There are two types of charges and they are positive charge and negative charge. (c) Like charges repel each other while the unlike charges attract each other.

## When an Ebonite rod is rubbed with a piece of flannel cloth the rod?

When you rub an ebonite rod against a cloth the rod gets negatively charged and the fur gets positively charged. This is because some of the atoms of the ebonite rod is deposited to the cloth. Thus, making it negative and increasing the no.

## What happens when flannel is rubbed over a glass rod?

When glass rod is rubbed with flannel cloth, positive charges is produced.

## Why can we not charge metal rod when held in hand and rubbed with wool?

A metal rod held in hand and rubbed with wool will not show any sign of being charged. Some substances readily allow passage of electricity through them, others do not. Those which allow electricity to pass through them easily are called conductors.

## Why does a charged glass rod attract a piece of paper?

Paper is a dielectric. When a positively charged glass rod is brought near it, atoms of paper get polarised , with center of negative charge of atoms coming closer to glass rod.

## Can a charged body attract another uncharged body?

Yes, a charged body attracts an uncharged body as the oppositely charged bodies attract each other.

## What is the charge of paper?

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 causes paper to stick to a pen that has been rubbed with a cloth?

The friction created by rubbing the pen against another surface causes electrons to be transferred, leaving the pen or straw electrically charged. Rubbing the pen on fabric most likely left it with a negative charge.

## Why is comb attracted to paper?

ANSWER: The paper is initially attracted to the comb because the comb causes separation of charge in the paper. The part of the paper pieces with positive charge is attracted to the comb. When the paper touches the comb, some of the excess negative charge in the comb is transferred to the paper.

## Why does the comb lose that ability after a few minutes?

Why does the comb lose that ability after a few minutes? The comb loses its charge to its sur- roundings and becomes neutral once again.

## What will happen if during induction the charging body was removed first before the ground connection?

The ground connection is broken before the charged rod is removed, leaving the sphere with an excess charge opposite to that of the rod. Again, an opposite charge is achieved when charging by induction, and the charged rod loses none of its excess charge.
