The nuclei of atoms are held together by the nuclear force. The neutrons in the nucleus assist this force.
When two pieces of metal repel each other, it is because of the interaction between their electrons. Like charges, such as the negative charges on electrons, repel each other according to the laws of electromagnetism. The electrons in the atoms of the metals create an electromagnetic force that pushes the two pieces apart.
Two positive charges will repel each other because like charges repel. This is due to the electric force between them pushing them apart.
The negative charges of their electrons repel each other.
The negative charges of their electrons repel each other.
Two objects that are of like charge will repel each other.
Attraction or repulsion of electric charges is called electrostatic force. This force can either attract opposite charges together or repel like charges apart.
like charges repel
If the atoms have opposite charges (positive to negative) they will attract. If the atoms have the same charges (positive to positive or negative to negative) then they will repel. You can look at the Law of Electric Charges to get more information on this.
When two positive charges touch, they will repel each other due to the like charges. This repulsion will cause the charges to move apart and try to reach a state of equilibrium where they are as far apart as possible to minimize the repulsive force between them.
repel
I believe that they will push away from each other. Only opposites attract.
Opposite charges attract because they have an electrostatic force that pulls them together, whereas like charges repel because they have a force that pushes them apart. This behavior is due to the exchange of virtual photons between the charged particles, leading to the creation of an electric field.
