Electrostatics is a branch of physics that deals with study of the electric charges at rest.
Since classical physics, it has been known that some materials such as amber attract lightweight particles after rubbing. The Greekword for amber, ήλεκτρον, or electron, was the source of the word 'electricity'. Electrostatic phenomena arise from theforces that electric charges exert on each other. Such forces are described by Coulomb's law. Even though electrostatically induced forces seem to be rather weak, some electrostatic forces such as the one between an electron and a proton, that together make up a hydrogen atom, is about 36 orders of magnitude stronger than the gravitationalforce acting between them.
There are many examples of electrostatic phenomena, from those as simple as the attraction of the plastic wrap to your hand after you remove it from a package to the apparently spontaneous explosion of grain silos, the damage of electronic components during manufacturing, and photocopier &laser printer operation. Electrostatics involves the buildup of charge on the surface of objects due to contact with other surfaces. Although charge exchange happens whenever any two surfaces contact and separate, the effects of charge exchange are usually only noticed when at least one of the surfaces has a high resistance to electrical flow. This is because the charges that transfer are trapped there for a time long enough for their effects to be observed. These charges then remain on the object until they either bleed off to ground or are quickly neutralized by adischarge: e.g., the familiar phenomenon of a static 'shock' is caused by the neutralization of charge built up in the body from contact with insulated surfaces
