Detailed explanation-1: -The SI unit of electric force is Newton (N). The SI unit of force is always Newton. Its Si unit is NC or can be said as Newton per Coulomb.
Detailed explanation-2: -In 1826 he published “The Mathematical Theory of Electrodynamic Phenomena Deduced Solely from Experiment”, a book in which he states that “magnetism is electricity in motion” and “magnetic phenomena depend only on the existence and motion of electrical charges”.
Detailed explanation-3: -Electric Force Equation. Using the equation: F=q*E it is clear that the electric force and field share the same direction when the electric charge q is positive while they oppose each other when the electric charge q is negative.
Detailed explanation-4: -The Coulomb constant, the electric force constant, or the electrostatic constant (denoted ke, k or K) is a proportionality constant in electrostatics equations. In SI base units it is equal to 8.9875517923(14)×109 kg⋅m3⋅s−4⋅A−2.
