When a rubber rod is rubbed with wool the rod becomes negatively charged where did the electrons that gave the rubber its negative charge come from?

When the rod becomes negatively charged, you can conclude that the magnitude of the wool’s charge is going to be equal to that of the plastic rod, because when the rod dups against the wool, some of the wool’s electrons are transferred to the rod, giving the rod a certain amount of negative charge, and the wool loses …

What happens when a rubber rod is rubbed against a cloth?

Let’s come up with a name for the thing that gets transferred between a rod and the material it was rubbed with. We can call it charge. … When 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.

What happens when you rub a metal rod with wool?

When wool is rubbed with a metal rod, the electrons come off and stick to the metal rod because it has more affinity for the electron, and thus here wool acquires a positive charge while the metal rod acquires a negative charge.

Why a rubber rod becomes negatively charged when rubbed with fur?

Molecules in the fur have a stronger attraction for electrons than the molecules in the rubber rod. 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.

How does a rubber rod become negatively charged?

How does a rubber rod become negatively charged through friction? It touches a negatively charged object, and protons move off of the rod. … It is rubbed with another object, and electrons move onto the rod. It is rubbed with another object, and protons move off of the rod.

What is attracted to a plastic rod rubbed with wool?

When rubbed with wool, lucite charges positive. … 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.

Is wool positively or negatively charged?

Certain types of objects seem particularly adept at being charged. Silk tends to give things a positive charge, and wool tends to give a negative charge.

When wool and plastic are rubbed together the plastic becomes?

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?

In case of the plastic rod and the fur, the negatively charged electrons from fur move to the plastic rod making it negatively charged and simultaneously leaving the fur with concentration of positively charged particles.

What would happen if a plastic rod rubbed with fur is brought near the glass rod rubbed with silk?

A plastic rod when rubbed with fur becomes negatively charged and a glass rod when rubbed with silk becomes positively charged.

Can ebonite be charged by rubbing?

When an ebonite rod is held in hand, it can be charged by rubbing with a flannel. This happens because the ebonite rod is a bad conductor of electricity. Due to this, the charges stay on the rod. On the other hand, when a copper rod is held in hand, it cannot be charged by rubbing with a flannel.

When a plastic rod is rubbed with wool do both the objects get charged in the process or only the plastic rod gets charged mention the charge acquired by the plastic rod?

When an ebonite rod is rubbed with wool, the rod becomes negatively charged. When a polythene piece is rubbed with wool, it acquires negative charge.

When you rub a plastic rod by animal fur it will be?

What happens to a plastic rod when it is rubbed with a piece of animal fur? What happens to the piece of fur? The plastic rod becomes negative, and the fur becomes positive. Magnitude stays the same.

What happens when we rub glass rod with silk?

Solution: When a glass rod is rubbed with silk, glass rod loses electrons and silk gains electrons. Glass rod becomes positively charged and silk becomes negatively charged. … On rubbing together, the glass rod loses 2 electrons and silk gains 2 electrons.

Why can plastic become charged if you rub it but not metal?

Explanation: When you rub plastic, you transfer electrons from one material to the other. … Because plastic is an insulator, the electrons cannot flow through it so they effectively get stuck there – they are static. In a metal, the electrons would get conducted away (e.g. back to the material they have come from).

When a rubber 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.

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

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.

What kind of charges are produced on each when Ebonite rod is rubbed with wool?

When an ebonite rod is rubbed with wool, then the ebonite rod becomes negatively charged while the wool becomes positively charged. This is because the electrons in wool are less tightly bound than the electrons in ebonite rod. So, friction between the wool and the rod makes the rod to gain electrons from the wool.
