Electromagnetic force is one of the fundamental interaction in universe comprise with electric field and magnetic field. there are three  Fundamental interaction  in universe. strong interaction, weak force, electromagnetic force and gravitation . Though, in special theory of relativity there have no explanation about gravitation, but Einstein explained gravitation. In grand unification theorem there have been focussed on unifying all of the fundamental interaction in a one unique continume.

Electrostatic force Electrostatic force means a force between two particles with charge. Two charged particles if with same electric charge excerts a force between themselves is repulsive force.  The examples of repulsive force between two same particles with positive charge. This types of repulsion is found in repulsion of alpha particles to  Nucleus in Rutherfords alpha particle scattering experiment when alpha particles are allowed to pass through the atom. Two particles with opposite charges attract each other. The force excerts between themselves is attractive force. In atom the attraction between revolving electron with nucleus is attracrive force. According to direction of force of electron within Nucleus , electrostatic force are in two types. Centripetal force that leads electron to collapse with nucleus and directed toward nucleus. Though, electron never collapses with nucleus. This collapsing is restricted by another force with opposite direction is called centrifu...

Nucleus is a centre of an atom. It is a positively charged element of an atom. Nucleus consists with positively charged proton and charge nutral neutron. Hence, it belongs positive charge.  In  Rutherford atomic model it termed as positively charged. The entire mass of an atom is concentrated into nucleus.  How number of proton consists in nucleus same number of negatively charged electron revolves surrounding nucleus.  When difference of charge between nucleus and electron is found then atom converts into Ion.  Rapid speed of motion of electron that is revolving surrounding nucleus is not getting displaced or collapsing. This is a result of  electrostatic force between electron and nucleus. Two electrostatic force excerts here is called centrifugal force and centripetal force which are same.
