*In this video, Coulomb’s Law and the concept of electric field are explained with a solved example for better understanding.*
*In the later part of the video, real-world applications—such as laser printers and electrostatic precipitators—are illustrated to show how electrostatic charges and the forces between them play a crucial role.*
*Following Topics are covered in the video*
0:00 What is Electrostatics? Coulomb's Law Explained
9:14 Electric Field Intensity Explained
11:40 Solved Example
18:42 How electrostatic precipitator and a laser printer work based on Coulomb’s law
_What is Electrostatics?_
Electrostatics is the branch of electromagnetics that deals with electric charges at rest and the forces, fields, and potentials associated with them.
_Coulomb's Law_
The electrostatic Force between the two point charges Q1 and Q2 is directly proportional to the product of the Q1 and Q2 and it is inversely proportional to the square of the distance R between them.
Mathematically, the electrostatic force F between two charges can be given as
F = k Q1Q2 / R²
Unit - Newton (N)
_Electric Field Intensity_
Electric field intensity at a given point is defined as the force experienced per unit positive test charge placed at that point.
E = F / Qt, where, Qt is a test charge
Unit - N / C or V/m
