Now, let’s look at the list of chapters from your 12th class physics textbook:

## Chapter 12 – Electrostatics Notes

Content: Short and Long Answers | Solved Exercises | MCQs

The first chapter is about electrostatistics – a branch of physics that studies electric charges at rest.

• Coulomb’s Law
• Coulomb’s Law is an equation from physics. It explains how two things with electric charge, that are very close together, will interact. If they have the same kind of charge, they will push away from each other. If they have different kinds of charge, they will be pulled towards each other.
• Coulomb’s Law is a bit like Newton’s Gravity Law. But there are some differences. Coulomb’s Law explains electric forces instead of gravity forces. And it works for much smaller distances than gravity does.
• Coulomb’s Law: Definition & Examples
• Coulomb’s law is the mathematical equation that describes the force of attraction or repulsion between two point electric charges. A charged particle’s electrostatic force is directly proportional to their electric charges and inversely proportional to their distance.
• The equation for Coulomb’s law is similar to Newton’s universal law of gravitation, which describes gravitational forces. This makes sense because both electric forces and gravitational forces are conservative forces, meaning the work done by these forces does not depend on the path taken, but only on the initial and final positions.
• Thus, we can treat electric forces as a function of distance only. In addition, work done by an electric force can be calculated using Coulomb’s law.
• Basic Forces of Nature
• Electric Field Lines
• Guass’s Law
• Much more!

## Chapter 13 – Current Electricity Notes
