The electrostatic forces between two objects that have the same kind of charge
act in the direction to push the objects apart.
A positively charged object will cause the leaves of the electroscope to separate or diverge. A negatively charged object will cause the leaves to come together or converge.
The positively charged object will be attracted to the negatively charged object, as opposite charges attract each other. The force of attraction between the two objects will cause them to move towards each other until they come into contact or until the force is balanced by another factor.
When a charged object is brought close to another oppositely charged object, they will experience an attractive force due to the difference in charge. If they are allowed to come into contact, electrons will transfer from the negatively charged object to the positively charged object until they reach equilibrium in charge distribution. This transfer of electrons will neutralize the objects.
When a positively charged object and a negatively charged object are near each other, they experience an attractive force due to their opposite charges. This attraction causes them to move closer together, and if they are close enough, they can transfer charge and neutralize each other. As a result, they may eventually come to a state of equilibrium, where their charges balance out, leading to a neutral state.
They would be strongly attracted to each other. Multiple such attractions are what hold together solid sodium chloride.
The object with more charge will repel the object with less charge due to the electrostatic force. This is because like charges repel each other. The objects will not come into contact and will instead push away from each other.
When two objects made of different materials come into contact, electrons can transfer from one object to the other due to the difference in their electron affinity. If an object gains electrons, it becomes negatively charged as it now has an excess of negative charges.
Charging a neutral object by touching it with a charged rod is called charging by conduction. The charged rod transfers some of its charge to the neutral object when they come into contact.
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.
Objects can become charged through friction, conduction, or induction. Through friction, electrons can be transferred between two objects by rubbing them together, resulting in one object becoming positively charged and the other negatively charged. In conduction, charges are transferred when objects come into direct contact with each other. Induction involves creating a charged region on an object without direct contact by bringing a charged object close to it, which causes a redistribution of charges within the object.
Most of the time, in an object, its negative and positive charges are balanced, which makes it a neutrally-charged object. Sometimes, when some objects come into contact with other things, they gather more charges of one type. If there are more electrons, they are negatively-charged. If there are more protons, they are positively-charged. Because opposites attract, an object which is negatively-charged will attract another object which is positively-charged and vice versa.
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.
