why do protons repel protons but attract electrons
Later people encountered many other phenomena and in the process of making a new hypothesis they had a constraint that it has to be consistent with the old theory and the assumption of the existence of lines of force coming in or out from a particular charged particle whose direction is associated to the nature of the particle and is seemed to serve the purpose. We are pretty sure that is true from the numerous experiments done. Here comes my concern, we know that the lines of force emerge from the charged particles but what is the cause for the emergence of lines in the first place? I agree that it is fundamental to assume such a thing to exist but can t this be investigated further? Isn t it a valid question? After all fundamental assumption is also called a belief but an acceptable belief. The reason for giving it such a status of being acceptable is that it is helping us understand the other phenomena. But we don t know the cause for such a belief or what exists beyond that belief.
The fundamental assumptions or the accepted beliefs are the points where we stop thinking about anything because when we accept something we won t find any need to think about it. It must not be the case, we must reason or investigate the existence of anything, of course only from the knowledge we acquired, then we will find the cause for it and only then it will lead us to the ultimate truth.
How does static electricity work? charges in objects. Have you ever walked across the room to pet your dog, but got a shock instead? Perhaps you took your hat off on a dry winter's day and had a hair raising experience! Or, maybe you have made a balloon stick on the wall after rubbing it against your clothes? Why do these things happen? Is it magic? No, it's not magic; it's static electricity! Before understanding static electricity, we first need to understand the basics of atoms and magnetism. All physical objects are made up of atoms. Inside an atom are protons, electrons and neutrons.
The protons are positively charged, the electrons are negatively charged, and the neutrons are neutral. Therefore, all things are made up of charges. Opposite charges attract each other (negative to positive). Like charges repel each other (positive to positive or negative to negative). Most of the time positive and negative charges are balanced in an object, which makes that object neutral. Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. One way to discharge them is through a circuit. The rubbing of certain materials against one another can transfer negative charges, or electrons. For example, if you rub your shoe on the carpet, your body collects extra electrons. The electrons cling to your body until they can be released. As you reach and touch your furry friend, you get a shock.
Don't worry, it is only the surplus electrons being released from you to your unsuspecting pet. And what about that hair raising experience? As you remove your hat, electrons are transferred from hat to hair, creating that interesting hairdo! Remember, objects with the same charge repel each other. Because they have the same charge, your hair will stand on end. Your hairs are simply trying to get as far away from each other as possible! When you rub a balloon against your clothes and it sticks to the wall, you are adding a surplus of electrons (negative charges) to the surface of the balloon. The wall is now more positively charged than the balloon. As the two come in contact, the balloon will stick because of the rule that opposites attract (positive to negative).
