# Quick Answer: What Happens When You Rub A Glass Rod With Wool?

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

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

## Why does a glass rod becomes positively charged?

The core has positive charge, the electrons have negative charge. 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.

Describe the force when the charges are like charges and the force when the charges are opposite charges. Electric force is directly related to each charge. … Electric force is inversely related to the square of the distance between charges. If the distance is tripled, the force will be one-ninth as great.

## What happens if two objects have the same charge?

Having the same type of charge, they will repel. … Charged and neutral objects always attract each other.

## What happens when two glass rods are rubbed with silk and they are brought close to each other?

What happens when two glass rods are rubbed with silk and they are brought close to each other? They repel each other.

## Why can a charged object attract a neutral object?

Neutral object are attracted to either charge. … The region that has too many electrons is negatively charged, the other region positively, because of lack of electrons. The positive region since it is closer to the charge will be attracted to this charge. This process is called induction.

## When a plastic rod is rubbed with wool?

Charging the plastic rod negative by rubbing it with the wool exciter leaves a net positive charge on the wool, so that if you place the rod on a swivel stand, you can then bring the wool exciter close to it and pull it around on the swivel stand. You can, of course, do the same thing with the glass rod and the silk.

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

What happens when you rub a cop- per rod with wool? Because the copper is a conductor, it remains neutral as long as it is in con- tact with your hand.

## Is hair positive or negative?

Electrons have a negative charge, so your hair has a small positive charge when a few electrons leave it. Positive charges repel each other, so your charged hairs repel each other and stand out from your head.

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

By convention, we call one type of charge “positive”, and the other type “negative.” For example, when glass is rubbed with silk, the glass becomes positively charged and the silk negatively charged.

## Is Wool positive or negative?

Wool is a conductive material, which means it readily gives away its electrons. Consequently, when you rub a balloon on wool, this causes the electrons to move from the wool to the balloon’s surface. The rubbed part of the balloon now has a negative charge.

## What are 3 examples of static?

What are three examples of static electricity? (Some examples might include: walking across a carpet and touching a metal door handle and pulling your hat off and having your hair stand on end.) When is there a positive charge? (A positive charge occurs when there is a shortage of electrons.)

## Why does an Ebonite rod get negatively charged on rubbing with wool?

On rubbing the ebonite rod with fur electrons move from fur to the ebonite rod. That is electrons in fur are less tightly bound than electrons in ebonite and hence ebonite gets a negative.

## What could make the fur become positive while the rod became negative when they are rubbed together?

Rod has its electron more tightly bound than fur. So, fur donates electrons to the rod while electrons from rod won’t come out. Due to excess of electrons in rod, it becomes negatively charged while the fur with lost electrons, becomes deficient of electrons. Thus, fur becomes positively charged.

## What happens when you rub a glass rod with fur?

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

## When a glass rod is rubbed with silk it acquires?

When 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 when you rub a copper rod with cloth?

On rubbing a copper rod with cloth is becomes positively charged. It gets charged due to friction, therefore, it will start attracting small bits of paper as it acquires a small number of electrostatic charges. However, it lasts only for a small period of time and soon the rod loses all its charge.

## When a glass rod is rubbed with silk the rod becomes positively charged This happens because?

When a glass rod is rubbed with silk it (the rod) becomes positively charged. This happens because: A) electrons are created on the rod.

## When a glass rod is rubbed against silk Which of the following statements is true?

The textbook tells us that when a glass rod is rubbed with silk, the glass rod becomes positive and the silk becomes negative. And so this means, electrons are removed from the rod so that there are more protons on the rod than there are electrons. And so it becomes positive and electrons must be removed to do that.
