INTRODUCTION TO ELECTROSTATIC
In this modern world, electrostatic plays an important role in several fields. There are many laws related to electrostatic field, however, there are two fundamental laws, which is Coulomb’s Law and Gauss’s Law. Gauss’s Law can be used to derive Coulomb’s Law, and Coulomb’s Law is also can be used to derive Gauss’s Law.
Coulomb’s Law
Coulomb's law is a law of physics describing the electrostatic interaction between electrically charged particles. It was studied and first published in 1783 by French physicist Charles Augustin de Coulomb and was essential for the development of the theory of electromagnetism.
It deals with the force a point charge exerts on another point charge. A point charge means a charge that is located on a body whose dimensions are much smaller than other relevant dimensions. For example, a collection of electric charges on a pinhead can be regarded as a point charge. Charges are generally measured in coulombs(C). One coulomb is approximately
