Question: Why Does An Ebonite Rod Get Negatively Charged On Rubbing With Wool?

What would happen when a glass rod is rubbed with fur?

1)As an example of the friction method, a glass rod rubbed with fur becomes negatively charged, but if rubbed with silk, becomes positively charged.

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..

When a plastic rod is rubbed with wool?

When wool is rubbed against a PVC (a type of plastic) strip, the PVC steals electrons from the wool because it has a greater attraction for electrons than wool does. The PVC strip ends up with a negative charge while the wool ends up with a positive charge.

What charge does a glass rod acquire on being rubbed with silk cloth?

Figure 2. A glass rod becomes positively charged when rubbed with silk, while the silk becomes negatively charged.

What is happening when a negatively charged rod becomes grounded?

Any negatively charged object has an excess of electrons. If it is to have its charge removed, then it will have to lose its excess electrons. … These excess electrons subsequently spread about the surface of the person. This process of grounding works because excess electrons find each other repulsive.

When a negatively charged rod is brought near?

When two negatively charged objects are brought near each other, a repulsive force is produced. When two positively charged objects are brought near each other, a similar repulsive force is produced. When a negatively charged object is brought near a positively charged object, an attractive force is produced.

Do 2 neutral objects attract?

Interaction Between Charged and Neutral Objects The interaction between two oppositely charged objects is attractive. … Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.

What happens when an Ebonite rod is rubbed with wool?

On rubbing an ebonite rod with wool, the electrons from the wool get transferred to the ebonite rod. The wool gets a deficiency of electrons and so it gets positively charged. On the other hand, the ebonite rod gets excess electrons and hence it gets negatively charged.

Can a charged body attract an uncharged body?

Therefore a charged body will attract an uncharged body.

Why does a rubber rod become negatively charged when rubbed with fur?

Molecules in the rubber rod have a stronger attraction for electrons than the molecules in the fur. … During a charging by rubbing (or by friction) process, the material that becomes negatively charged does so because it simply likes electrons more than the material with which it is rubbed.

Why does a glass rod lose electrons when rubbed with silk?

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.

Why does an Ebonite rod is 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 kind of charges are produced when Ebonite rod is rubbed with wool?

The ebonite rod acquires negative charge and fur/wool acquires an equal positive charge.
