When A Glass Rod Is Rubbed With Silk And Becomes Positively Charged?

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..

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.

Why does an Ebonite rod becomes negatively charged on rubbing with fur?

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. The charge on ebonite rod is negative and the charge on fur is positive.

Is Silk negative or positive?

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.

What does it mean when the electric field lines are close together?

A line tangent to a field line indicates the direction of the electric field at that point. Where the field lines are close together, the electric field is stronger than where they are farther apart.

When a glass rod is rubbed by animal fur What are the respective charges on the respective items?

In the 18th century, American Ben Franklin noticed when a rubber rod is rubbed by animal fur, the rod acquires a negative charge, and the animal fur acquires a positive charge. When a glass rod is rubbed by silk, the rod acquires a positive charge and the silk obtains a negative charge.

What kind of charge is produced when a glass rod is 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.

When glass rod and silk cloth rubbed each other glass rod acquires positive charge and silk cloth negative charge work function of glass is?

the glass rod acquires a positive charge due to loss of electrons. the silk cloth acquires negative charge due to gain of electrons. if these two bodies are again brought in contact the net charge on them is zero.

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.

What happens when you rub a glass rod with wool?

Two positively charged objects repel each other, and the ball moves away from the glass when they are held in each other’s proximity. Then the glass rod is rubbed with the wool, and the wool sheds electrons onto the glass, giving it a negative charge.

What is the charge on a rubber rod rubbed with fur?

negative chargeWhen a rubber rod is rubbed with fur or felt electrons are transferred from the material to the rod, giving the rod a negative charge. Two negatively charged objects repel. When a positively charged object is brought near a negatively charged object the two objects attract one another.

What is the purpose of an Electroscope *?

The purpose of an electroscope is to detect the presence of charge on the body and nature of charge (whether its positively charged or negatively charged) on the body.

When a glass rod is rubbed with silk and becomes positively charged *?

What charge does the silk have? The rubbing will strip the atoms of the rod of their electrons, which are negatively charged, leaving the rod to be positively charged. The silk will acquire these extra electrons, becoming negatively charged. Describe electric current and identify the two types of current.

What happens when an Ebonite rod is rubbed with silk?

The ebonite becomes negatively charged, and the fur becomes positively charged indicates. Similarly, if a glass rod is rubbed with a silk cloth, some of the electrons are removed from the atoms of the glass and deposited on the silk, leaving the silk negatively charged and the glass positively charged.

What happens when an Ebonite rod rubbed with fur and a glass rod rubbed with silk are brought near each other?

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.

When you rub a plastic rod with fur?

If we rub the Plastic Rod with the Fur, Negative Charges are transferred from the Fur to the Rod. The Rod is negatively charged and the Fur is positively charged. Electroscope is an electrical instrument for indicating the Electric Charge, Figure 2(a).

What are two factors that affect the electric force between two charged objects?

The first factor is the amount of charge on each object. The greater the charge, the greater the electric force. The second factor is the distance between the charges. The closer together the charges are, the greater the electric force is.

What occurs when two charges are moved closer together?

What occurs when two charges are moved closer together? … The total charge increases. The force between the charges increases.
