The acetate rod loses electrons and becomes positively charged.
Acetate is a material that becomes negatively charged when rubbed against hair, meaning it gains electrons. In contrast, hair becomes positively charged as it loses electrons during the rubbing process.
If you move the material near the negative acetate strip and they repel each other, the material negatively charged. If they move towards each other, it is positively charged. If you move the material near the positive rod and they attract, the material is negatively charged. If they repel, it is positively charged. This is because opposite charges attract and same charges repel.
The charge on the balloon would be -1.6 x 10^-12 coulombs.
Benjamin Franklin was the man that defined negative and positive charge. In the nineteenth century, positive and negative charge was known as vitreous and resinous charge, respectively.Franklin defined negative charge as the charge of a piece of amber after being rubbed against glass.
Short Answer: Because metal rods are conductors. This means that while they easily accept a charge, they also easily discharge. Thus, any charge that is applied to it will immediately discharge, resulting in zero potential. Long Answer: Search for 'tiboelectric series', 'electrostatics', and 'properties of conductors and insulators'. An in-depth answer would require a collegiate-level introduction to Physics and Calculus.
A polythene rod acquires a negative charge when rubbed with a duster. This is because electrons are transferred from the duster to the polythene rod, leaving the rod with an excess of electrons and a negative charge.
When an acetate strip is charged by rubbing, it acquires a negative charge. This is because acetate is a type of material that tends to lose electrons easily when rubbed, causing it to become negatively charged.
The two polythene rods will repel each other. This is because when the rods are rubbed, they acquire a net positive charge which causes them to repel each other since like charges repel.
When glass is rubbed, it tends to acquire a negative charge. This is due to the transfer of electrons from the material it is rubbed against to the glass, causing an imbalance in charge and resulting in a negative charge on the glass.
When a glass rod is rubbed against a cotton duster, electrons are transferred from the glass rod to the duster. This leaves the glass rod with a net positive charge. The process is known as triboelectric charging, where materials gain or lose electrons during friction.
The ebonite rod acquires a negative charge when rubbed with woolen cloth because electrons are transferred from the woolen cloth to the ebonite rod.
When an ebonite rod is rubbed with flannel, the rod becomes charged with static electricity due to the transfer of electrons between the two materials. The ebonite rod will acquire a negative charge, while the flannel will acquire a positive charge.
When an object is rubbed with a duster, some of the atoms in the object lose or gain electrons through the friction of the rubbing process. This imbalance of electrons creates a charge difference between the object and the duster, leading to the generation of static electricity.
Both are originally have equal electrons and protons. After rubbing, electrons move to the duster, from the rod. The duster, as it gains electrons, has more electrons than protons, therefore becoming negatively charged. The rod, losing electrons, becomes negatively charged. then, the rod is able to momentarily pick up little bits of paper for short periods at a time.
The silk blouse will acquire a positive charge when rubbed with the wool socks due to the triboelectric effect. Wool has a tendency to lose electrons when rubbed against other materials, transferring a positive charge to the silk blouse.
When polythene is rubbed with a duster, electrons from the duster are transferred to the polythene rod, giving the rod an excess of electrons and making it negatively charged. This transfer of electrons creates an imbalance of positive and negative charges on the surfaces, resulting in the rod becoming negatively charged.
When you rub the comb against the duster it charges up the electrons,the electrons in the comb and the electrons in the water will repel
