The nearness of charge offers ascend to an electrostatic force: charges apply a force on each other, an impact that was known, however not understood, in antiquity. A lightweight ball suspended from a string can be charged by touching it with a glass pole that has itself been charged by scouring with a fabric. These phenomena were investigated in the late eighteenth century by Charles-Augustin de Coulomb, who reasoned that charge manifests itself in two contradicting forms. This disclosure prompted the notable axiom: like-charged items repulse and inverse charged articles attract.
The force acts on the charged particles themselves, henceforth charge has an inclination to spread itself as equally as conceivable over a leading surface. On the off chance that a similar ball is charged by the same glass pole, it is found to repulse the principal: the charge acts to force the two balls apart. Two balls that are charged with a scoured amber bar also repulse each other. Be that as it may, in the event that one ball is charged by the glass bar, and the other by an amber pole, the two balls are found to attract each other.
The magnitude of the electromagnetic force, whether attractive or loathsome, is given by Coulomb's law, which relates the force to the result of the charges and has an opposite square relation to the distance between them.The electromagnetic force is solid, second just in solidarity to the solid interaction,yet not at all like that force it operates over all distances.
