Thanks

Hai Jax Back,
It's NOT correct.
Actually, particles with LIKE charges repel each other, and particles with OPPOSITE charges attract each other.

Ooops, you have it bassackwards. Opposites attract and likes repel. So if you have two negative charges they will repel each other according to F = kqq/r^2; if they are opposite charges (like a proton and an electron) the F force will be attractive.
Now to your question...why do the forces reverse depending on the sameness or different charges? These charges transmit a force field via messenger particles. This simply means that when the field intercepts something, it will exert a force on that something. Think of the field as being a bunch of tiny arrows pointing together in the same direction.
When two like charges are close together, the two force fields act in opposite directions; so the net effect is to repel each other. When two different charges are close together, the two force fields act in the same direction. The net effect is to attract each other then.
By the way, it's because of the fields that the force diminishes as the inverse of the square of the distance between the charges. That is, the force field density diminishes as the area through which the field travels increases. And that area gets larger by the square of the distance r from the source of the field.

It can be explained on the basis of magnetic lines created or emerging out of the charge particles.
The positive charges have magnetic lines coming out and negative charges have magnetic lines going in radially, so when the same charges are near there lines repel because of the same configuration. However when a positive charge is brought near to a negative charge, the magnetic lines form a close loop where the emerge from positive charge and end into negative charge, so they attract.
I hope it helps.

There is not so much as an attempt to explain this in the standard model.
I have been working on a possible explanation. It's too long to post here; I have 3 minutes left on internet today. Try the link, below.

No, like charges repel but opposite charges attract, because if something has a minus charge it will be attracted to something with a plus charge, ie. opposite charges have been attracted..!!!

They almost always don't.
However, if you're thinking about at the quantum level, protons (+ve charge) in the nucleus are kept together by another force, they don't actually attract each other.

same as the like poles on a magnet.
