When a plastic rod is rubbed with a wool cloth the plastic rod becomes negatively charged because?

A B
An object is charged positively when rubbed with a piece of silk. The object became charged by losing electrons
When a plastic rod is rubbed with wool, the wool acquires a positive charge because electrons are transferred from the wool to the rod.

Why does a plastic rod become negatively charged?

Electrons can be made to move from one object to another. … For example, when a plastic rod is rubbed with a duster, electrons are transferred from one material to the other. The material that gains electrons becomes negatively charged.

When you rub a plastic rod with fur The plastic rod becomes negatively charged and the fur becomes positively charged?

When you rub a plastic rod with fur, the plastic rod becomes negatively charged and the fur becomes positively charged. 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.

When a plastic rod is rubbed with fur the rod will become negatively charged Which of the following best explains how this happens?

2 When a plastic rod is rubbed with fur, the rod will become negatively charged. Which of the following best explains how this happens? a Electrons are transferred from the plastic rod to the fur.

What happens when a plastic rod is rubbed with wool?

When a platic rod is rubbed with wool the rod gains negative charge and wool gains positive charge . So the rod repels negative charge from the top of the electroscope this causes excess of negative charge on leave the leaves having the same charge are repelled and dilated.

What happens to the electrons when a plastic rod is charged negatively using 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.

What happens when you rub a rod with a cloth?

The material that gains electrons becomes negatively charged. The material that loses electrons is left with a positive charge. When a polythene rod is rubbed with a duster, the friction causes electrons to gain energy. Electrons gain enough energy to leave the atom and ‘rub off’ onto the polythene rod.

Does plastic have a positive or negative charge?

Choice of the names negative or positive is arbitrary. If you rub a glass rod with a cloth, the charge produced on the glass rod is called positive, whereas when a plastic rod is rubbed with a cloth, the charge produced on the plastic rod is negative.

What happens when a negatively charged rod is brought near a positively charged Electroscope?

When a negatively charged object is brought near a positively charged object, an attractive force is produced. … Since both leaves are negatively charged, they repel each other. When the rod is removed, the electroscope will remain charged because of the extra electrons added to it.

When a plastic rod is rubbed with wool the wool becomes positively charged because?

Electricity and Magnetism Test

A B
When a plastic rod is rubbed with wool, the wool acquires a positive charge because electrons are transferred from the wool to the rod.
How is a positive charge usually given to a neutral object? electrons are removed from the object.

What happens 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. … The charge distribution on an object can be changed by other charged object.

What do you call the process of removing excess charges on an object?

Grounding is the process of removing the excess charge on an object by means of the transfer of electrons between it and another object of substantial size. When a charged object is grounded, the excess charge is balanced by the transfer of electrons between the charged object and a ground.

Why do charged and uncharged objects attract?

When we put a charged object near an uncharged object, it produces opposite charges in the near end of the uncharged object by electric induction. In the figure, we can see that glass rod is positively charged.

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.

Does wool have a positive or negative charge?

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.
