When a glass rod is rubbed in silk, it becomes positively charged. What happens to electrons?
When a glass rod is rubbed in silk, it loses electrons and gains electrons. Glass rod is positively charged, and silk is negatively charged. For example, suppose a glass rod has 10 protons and 10 electrons and silk has 7 electrons and 7 protons.
What happens if a glass rod is rubbed with silk?
A glass rod that is rubbed with silk will become positively charged, while silk will become negatively charged.
What happens when you rub a plastic rod with a cloth?
The choice of names positive or negative is arbitrary. A glass rod can be rubbed with a towel to produce a positive charge, while a plastic rod can be rubbed with a towel to create a negative charge.
What happens when you rub a plastic rod with wool?
56. 06 — Electrostatically charged rods. The rod charges negative when you rub it with the wool cloth (polyethylene Terephthalate, glycol modifed, or PETG). The rod will charge positive if you rub it with silk. He is the name of the Coulomb, which is an unit of electrostatic charges.
Why does a polythene rod become negatively charged when rubbed with a dry cloth?
When a piece made of polythene gets rubbed with a cloth it becomes charged. The friction of the cloth rubs the electrons off the cloth, and onto the polythene. This negatively charges the polythene and makes the cloth positive charged.
Why are negative and positive charges attracted to each other?
When a positive and a negative charge are in contact, their forces work in the same direction. They act from the positive towards the negative. Opposing charges attract one another. This is due to the electric field and resulting forces created by two different polarities of electrical charges. These two charges attract one another.
What is the strength of the electric field at twice the distance from the point charge?
What is the strength the electric field at twice as far from the point charge than the one that you are using? The field strength is E/2 at twice the distance.
