There are 2 lessons in this physics tutorial covering Coulomb's Law. The tutorial starts with an introduction to Coulomb's Law and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific physics lesson as required to build your physics knowledge of Coulomb's Law. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

  • The meaning of electrostatic force.
  • What are the factors affecting the electrostatic force?
  • What does the Coulomb's Law say?
  • How to find the electrostatic force?
  • How to find the equilibrium position between two charges?
  • How to calculate the resultant electrostatic force on a charge in 1-D?
  • How to calculate the resultant electrostatic force on a charge in 2-D?

Introduction

What physical quantity do the terms "attraction" and "repulsion" imply?

Do you think electric charges exert any force on each other? How do you know this?

Do you know how it is possible the atoms of solids stay together?

In this tutorial, we discuss about electrostatic force - a quantity that is responsible for the interaction between charges. Such an interaction was first observed and analysed by the French scientist Charles Coulomb during the 18th century. This is why the unit of electric charge holds his name.
