It is known that there is a force of repulsion (or attraction) between two similar (or dissimilar) charges and the laws governing these forces are well established in electrostatics. However, the exact mechanism and the origin for these forces are not known. The purpose of this investigation, therefore, is to reveal these aspects in the light of the presence of vibrating strings and lines of fields created by the negative (or positive) charge. The present approach strongly suggests that the force of repulsion is originated between two charges due to fields synchronized with vibrating strings. The Gauss symmetry seems to play a crucial role in these aspects.
