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.

How does A student puts a negatively charged object against a metal cabinet. Describe what happens to the charge on the object when it touches the metal cabinet?

Well the metal would obviously attract a charged particle for its charge less surface. The only possible way would be placing a positively charged object on the other side of the negative charged object such that it could counter effect the coulombian pull on the negative charge due to the metal. To keep the positive charge in place it would need to place it within oppositely charged electronic plates. This needs more amendments but thats another topic. When a charged object touches metal, the end result is usually what is known as a static shock.


What does it mean for an object to have electrical charge?

When an object has electrical charge, it means that it has an imbalance of positive or negative electrons. This imbalance creates an electric field around the object that can interact with other charged objects. Objects with the same charge repel each other, while objects with opposite charges attract each other.


Can electrons move from one object to another when rubbed together?

Yes, when two objects are rubbed together, electrons can move from one object to the other. This is known as triboelectric charging, where one object becomes positively charged (losing electrons) and the other becomes negatively charged (gaining electrons).


How does rubbing one object on another create static electricity?

the electrons get ripped off one object and held by the other The rubbing moves electrons to the object that holds them more tightly.


What is a metal that can attract other materials without touching them?

Iron, Nickel and cobalt are attracted to magnets, these are field forces because they act on an object without touching it

Why does a rubbed plastic object stay charged but a rubbed metal object lose its charge?

Rubbed plastic objects tend to hold onto their charge because they are insulators, meaning that they do not easily allow charge to flow. Rubbed metal objects, on the other hand, are conductors and can easily lose their charge as the electrons can move freely within the material and dissipate.


What type of charge transfer occurs when two objects are rubbed together?

When two objects are rubbed together, electrons can move from one object to another, causing a transfer of charge. This can result in one object becoming positively charged and the other becoming negatively charged.


Which of these move from one object to another when two objects are rubbed together?

Electrons move from one object to another when two objects are rubbed together, causing a transfer of charge. This transfer can result in one object becoming positively charged (loss of electrons) and the other becoming negatively charged (gain of electrons).


When two ojects are rubbed togetherwhat kind of charge gets moved to one another?

When two objects are rubbed together, electrons are typically moved from one object to the other. This can result in one object becoming negatively charged (gaining electrons) and the other becoming positively charged (losing electrons).

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.


How does gold-leaf electroscope works?

A gold-leaf electroscope works by using charged objects to induce a charge on the metal leaves, causing them to repel each other and diverge. When a charged object is brought near the electroscope, it either transfers electrons to or takes electrons from the metal leaves, causing them to acquire a charge of the same polarity as the charging object. This charge separation results in the metal leaves repelling each other and diverging, indicating the presence of a charge.


The transfer of charge from one object to another by rubbing?

This is known as triboelectric charging, where two objects acquire an electric charge through frictional contact. When two objects with different levels of electron affinity come into contact and are rubbed together, electrons can transfer from one object to the other, resulting in one object becoming positively charged and the other becoming negatively charged.


How is an electric charge transferred by friction?

When two objects are rubbed together through friction, electrons can transfer from one object to the other. This transfer of electrons creates an electric charge imbalance on the surfaces of the objects, leading to one becoming positively charged and the other negatively charged.


When a silk blouse and wool socks are put into the dryer what charge will appear on the blouse when rubbed with the socks?

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.


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.
