Electric field

[Rare]

May i request for 2D simulation that have the purpose of showing theoretical predictions from Coulomb's law ( recall and use Coulomb's law in the form F = Q1Q2/4πε_or ^2 for the force between two point charges in free space or air), please? I would like all parameters to be changed. I would like F to be calculate. Unit of Q in C, unit of r in m, unit of ε_o in Fm^-1 & unit of F in N. Thank you so much

What you need is a calculator.
Coulomb can be expressed as
where .

What you want is not realistic.
For example: It is not easy to accumuate charge as at one point with charge 1C.
If there are two charge both are 1C and separate by 1m, the force between them is
,which is also like the weight of mass=.  This is not realistic. There is no way you can hold those two chartge at fix 1m distance.

I do not understand what is the purpose of your request?
If you just need to practice the calculation, you should just use a calculator.

my purpose is for inquiry learning.

Could you be more specific about your objective?
What you want user to be able to do with it and what you hope user can learn from it?
Are you a teacher? Could you shom me what might be the worksheet or learning activities look like?

It will be better if you can provide more information.
If I can fully understand what you really want, I would be able to produce simulations really fit with what you need.

Hi Rare,
maybe u need this applet as the base for your request.
so now you can add the forces on the 2 charges?
is this what you want?
