Introduction
There exists a force between the two charges, but what happens when we remove one charge from the system?
Pre-Requisites:
Knowledge about coulomb’s law.
Activity:
Find out on which quantities electrical field due to charge depend.
Real Life Question:
What is the thing which is responsible for the force between the charges?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Electrical Field Test Charge | It is the force experienced by a unit positive charge in the system. The charge which is brought near the source charge to observe the effect of field. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Book | You can learn more about this from your text book. |
Real life uses :
Microphones, Electric guitar, Hydro power plants etc.
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, there exists a field by charges, which affect force. |
What you learn in Theory:
There exists a field even when only one charge is present in the system, which is directed outwards for positive charge and directed inwards for negative charge.
What you learn in Practice:
The field existing due to the charge is responsible of force between two charges, when another charge is brought near the source charge.
