How can you explain the presence of a charge on the rubber rod after it has been rubbed with wool?
When the rubber rod is rubbed with wool, electrons are transferred from the wool to the rubber, leaving the rubber with a net positive charge. This occurs because the rubber has a higher affinity for electrons compared to wool. The excess electrons on the rubber rod result in a net negative charge, as the positive charge was neutralized by the transfer of electrons.
Why does a glass rod get positively charged when rubbed with rubber?
When a glass rod is rubbed with rubber, electrons are transferred from the glass to the rubber due to differences in their electronegativities. This leaves the glass rod with a net positive charge, as it has lost electrons.
What happens when a rubber rod is rubbed with a piece of fur?
normally, the rubber rod and the peice of fur has an equal number of protons and electrons, making each balanced. When you rub these two together, the rubber rod takes on electrons from the fur, giving the rod more electrons than normal. A negative charge, where as the fur loses electrons creating a positive charge.
When a rubber rod is rubbed with wool the rod becomes negatively charged?
When a rubber rod is rubbed with wool, electrons are transferred from the wool to the rubber rod, causing the rubber rod to become negatively charged. This transfer of electrons creates an imbalance of charge on the two materials, resulting in the rubber rod being negatively charged.
Why must your touch a charged object to the metal rod of an electroscope and not the rubber stopper?
You must touch a charged object to the metal rod of an electroscope because metal is a good conductor of electricity, allowing the charge to flow through it. The electrons from the charged object redistribute along the metal rod and into the leaves of the electroscope, causing them to repel. Rubber, on the other hand, is an insulator and does not allow the charge to flow.

Why rubber rod will attract small pellets of styrofoam?
A rubber rod can attract small pellets of styrofoam due to the process of static electricity. When the rubber rod is rubbed with a cloth or another material, it becomes negatively charged by gaining electrons. The styrofoam pellets, being neutral, can become polarized in the presence of the charged rubber rod, resulting in a temporary positive charge on the side closest to the rod. This attraction between the oppositely charged areas causes the styrofoam pellets to be drawn towards the rubber rod.
When a rubber rod is rubbed with wool the rod becomes negatively charged?
When a rubber rod is rubbed with wool, electrons are transferred from the wool to the rubber rod, causing the rubber rod to become negatively charged. This transfer of electrons creates an imbalance of charge on the two materials, resulting in the rubber rod being negatively charged.
A negatively charged rubber rod can pick up small neutrally charged pieces of paper by a process called what?
The process by which a negatively charged rubber rod picks up small neutrally charged pieces of paper is called electrostatic induction. When the rod approaches the neutral paper, it causes the electrons in the paper to move away from the rod, creating a positive charge on the side nearest to the rod. This induced positive charge then attracts the negatively charged rod, allowing it to pick up the paper.

Why is it important to touch the object to the metal rod and not the rubber stopper?
It's important to touch the object to the metal rod and not the rubber stopper because metal is a good conductor of electricity, allowing any static charge to be neutralized. Rubber is an insulator, so it doesn't allow the charge to flow and can cause a buildup of static electricity on the object. This can lead to potential shocks or other hazards.
Why copper rod cannot be charged?
Because Copper is a conductor and conductors do not hold electricity. The charge flows out. But, A copper rod can be charged if it is in a rubber handle. This will result in the charge staying in the rod, thus charging it.
Is a metal rod easy to charge with static electricity?
Yes, metal is a good conductor of electricity and therefore does not tend to hold a charge well. It is harder to build up a significant static charge on a metal rod compared to other materials like plastics or rubber.
What happens when you bring a negatively charged rod near a piece of metal.?
protons in the metal move toward the rod.
How can one determine the linear charge density of a rod?
To determine the linear charge density of a rod, divide the total charge on the rod by the length of the rod. Linear charge density is measured in coulombs per meter.
