Introduction
Two charges in the vacuum exert force on each other, which can be calculated.
Pre-Requisites:
Basic properties of electric charges.
Activity:
Find out what are the conditions for coulomb’s law to be valid.
Real Life Question:
“What is the magnitude of charges, which is used to calculate the force between two point charges?”
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Point charges Coulomb’s law | Those charges whose size is much smaller as compared to the distance between them. It gives us expression to calculate the force between two point charges. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Book | You can learn more about coulomb’s law from your text book. |
Real life uses :
To calculate the Force between two point charges.
Places to visit :
Your school physics lab, you can also refer to your text book for more knowledge.
Practical examples around us
| Examples | Explainations |
|---|---|
| Every system of charges present | In every system of charges present in the universe, coulomb’s law is applied to calculate the force between these charges. |
What you learn in Theory:
When two point charges are present in the vacuum, the force between them is directly proportional to the product of charges and inversely proportionally to the square of distance between them.
What you learn in Practice:
There exists a force between any two charges present in this universe. Size of charges must be point sized in order to apply coulomb’s law.
