Why do like charges repel and unlike charges attract (in both static and current electricity)?

Question

In current electricity,one may say that electron flow in a conductor is just like water flow in a river---when water flows from the opposite ends of a ditch,it results in a collision,just like 2 electrons would if they were to move in opposite directions.But you see,water flowing in opposite directions collide or repel because the water has no other space,or volume,to occupy,other than the volume of the river.Had there been any other space,or volume,to occupy,then some of the water would have occupied the extra volume,& the collision would not be so prominent.This is what happens in case of electrons in motion---when 2 electrons,or 2 streams of electrons,flowing in opposite directions meet in a conductor,they have so much of extra space in the wire to occupy(as the volume of all the electrons flowing in the wire is negligible as compared to the volume of the wire), that a collision could easily be prevented.So why does it take place. I may be wrong with my reasoning,but please explain.

Answer 1

That is strictly due to the way that nature arranged physics after the big bang. You may as well ask, why does water run downhill and not up.
Also concerning your thought about water and electricity, don't forget that any matter, including water, is mostly space anyway. 99.99% space and .01% matter (which is really composed of forcefields, strictly speaking, that keep each other apart not dissimilar to the electric charges).

Answer 2

Electrons are formed of three parts. There is the mass comprising the southern half (offers resistance to movement), there is the electrical equator that bonds the electron and keeps it bonded, and there is the expanding magnetic lines of the northern half that equal the mass of the southern half.

Because the energy of the magnetic lines equals the mass of the southern half, a person is able to see that there are strong lines of influence reaching outward from an electron. The magnetic lines being proportional to the southern mass have an immediate influence on the entire electron (like the difference between towing a car with a rope or heavy chain). These lines of force extend far beyond the electron and, also, at oblique angles to direction of travel, so they take up a lot of "space". What causes electrons to repel each other is the direction of magnetic lines. They all spin counterclockwise, so when they meet moving from opposite directions, they lines mutually repel each other over long distances.

Answer 3

1) In all parts of your example you want to use "toward each other" instead of "away from/opposite direction". "Away from/opposite direction" means that they are moving away from each other and would not be able to interact because of decreasing proximity to each other.

2) Water is a compound substance with complex behaviors. When it hits another aqueous substance, it flows around it, so eventually the molecues in each mass mix completely though their mollecular structure retains their dignity--as opposed to bonding to each with covalence, etc. Even if the water were in a closed system with no room to move, the mixing would take place though without the help of splashing all around and the resulting waves interacting.

3) Particles of like polarity repel each other. Why? I have no idea. But the fact is known that electrons repel electrons, protons repel protons--which is why we need the "strong force" to keep the nuclei of atoms together; if there were no strong force, the intense repellant nature of the protons toward each other results in terriffic explosion. That process is purposely insitigated in nuclear bombs.

4) You are very smart to provide your conception and example further clarifying your question. Keep thinking that way and being so thorough, and you will go many good places in life.

Answer 4

The size of the electrons doesn't matter at all. Electrons repel each other just like the northpoles of 2 magnets repel. The magnets don't have to touch each other. It works from a distance.

Answer 5

Dear sir I think you got wrong
Let me tell you the phenomenon of colliding
It is just like a high speed car moving in opossite to another car and when they collide the have no chance avoid this colliding and they collide and go in other direction loosing some energy
Same case is for a electron when it collide it has no more chance to go due to high speed motion.


If it is not cleared then you can ask me again in more detail.

Answer 6

when two like charges are placed before each other there electrons want to clollide but the strong nuclear attraction they can't do that's why they repel each other

Answer 7

because ther is an attractive force between electrons and protons.

Answer 8

Because of their property.
