Enfp physical appearanceThrough the work of scientists in the late 18th century, the main features of the electrostatic force—the existence of two types of charge, the observation that like charges repel, unlike charges attract, and the decrease of force with distance—were eventually refined, and expressed as a mathematical formula.The mathematical formula for the electrostatic force is called Coulomb's law ...Theoretically, the net electrostatic force on a charged particle in an applied electric field can be written in a form consisting of three components, (2) F E =−αQ 2 /(16πε 0 R 2)+βQE−γπε 0 R 2 E 2, where Q is the net charge on the particle of radius R, E is the strength of externally applied electric field, and ε 0 is the permittivity of the medium surrounding the particle.
