Charged rod and an uncharged metal object attract each other because free electrons in metal are either attracted or repelled by the charged rod.
If the rod is positively charged then free electrons are attracted towards it and both objects attract each other.
If the rod is negatively charged then free electrons are repelled by it and positive ions are attracted by the rod and both objects attract each other.

Do metal objects get charged by conduction?
Yes, metal objects can become charged by conduction if they come into contact with a charged object. If a charged object is connected to a metal object, the excess charge can flow through the metal by conduction, causing the metal object to become charged.
What is an example of an object that can be charged by induction?
An example of an object that can be charged by induction is a metal sphere.
What happens to the electrons in a metal object when it is held near a negatively charged object?
The electrons in the metal object are repelled by the negatively charged object and will move away from it. This redistribution of electrons can create a temporary separation of charges on the surface of the metal object.
What happens when a charged electroscope is connected to an uncharged electroscope by a metal wire?
Charge would flow from the charged electroscope to the initially uncharged one, until the charges are equal on both. At that point, the potential on both ends of the wire would be equal, there would be no voltage across the wire, and no more current would flow. Both electroscopes would then be charged, with charge of the same sign, and with half as much charge as the initially-charged one had.
A charged object is brought near a metal ball that is mounted on a rubber sheet. If the metal ball acquired a negative charge after it was grounded momentarily what must be the charge of the object th?
If the metal ball acquired a negative charge after being grounded, the charged object must be positively charged. When grounded, the metal ball gained electrons which caused it to become negatively charged. This would only occur if the charged object had an excess of positive charge to transfer to the metal ball.
What happens wheharges in an uncharged metal object rearrang without direct contact with the charged object?
In that case, the fact that the charges are rearranged - there is an electric dipole - can cause the charged object and the object with the zero net charge (but with an electric dipole) to attract one another.
Do metal objects get charged by conduction?
Yes, metal objects can become charged by conduction if they come into contact with a charged object. If a charged object is connected to a metal object, the excess charge can flow through the metal by conduction, causing the metal object to become charged.

How can a balloon become charged and uncharged?
A balloon can become charged by rubbing it against a different material like wool or hair, causing a transfer of electrons. This imbalance of electrons creates a charge on the balloon. To discharge the balloon, it can be touched to a conductor like a metal object, allowing the excess electrons to flow away.
How does a gold leaf electroscope show that an object is charged?
When a charged object is brought near the metal disc of a gold leaf electroscope, electrons move between the metal disc and the gold leaf, causing the gold leaf to become charged with the same type of charge as the object. This results in the gold leaf repelling from the metal disc, indicating that the object is charged.
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.
If a metal object receives a positive chargedoes the mass of the object increasedecreaseor stay the same?
Object A is charged . Because the neutral objects do not repel or attract charged bodies..
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.
Do a negativity charged and neutral object repel?
No. But they can attract each other, provided the neutral object is a metal, in which case the negatively charged object will induce charges on it to cause the attraction.
