Expansion of Coulomb's law . Anyone explain it

Explanation:
The scalar form of Coulomb’s Law relates the magnitude and sign of the electrostatic force F, acting simultaneously on two point charges q1 and q2:
|F|=14πarϵ0|q1q2|r2|F|=14πarϵ0|q1q2|r2,

Lorentz Force on a Moving Particle: Lorentz force f on a charged particle (of charge q) in motion (instantaneous velocity v). The E field and B field vary in space and time.
where r is the separation distance and ε0 is electric permittivity. If the product q1q2is positive, the force between them is repulsive; if q1q2 is negative, the force between them is attractive. The principle of linear superposition allows the extension of Coulomb’s law to include any number of point charges—in order to derive the force on any one point charge by a vector addition of these individual forces acting alone on that point charge. The resulting force vector happens to be parallel to the electric field vector at that point, with that point charge removed.
