an electrostatic negative charge
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.
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.
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, 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.
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.

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.
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.
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.
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.
protons in the metal move toward the rod.

When a rubber rod is rubbed with wool, electrons are transferred from the wool to the rubber rod. This results in the rubber rod becoming negatively charged and the wool becoming positively charged. This phenomenon is known as triboelectric charging, where rubbing two materials together causes the transfer of electrons between them.
