Electric field inside a charged insulator

Click For Summary

Homework Help Overview

The discussion revolves around determining the electric field inside a charged insulator, specifically as a function of position x. Participants are exploring the relationship between the electric field inside and outside the insulator.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the linearity of the electric field from x = 0 to x = d/2 and question how this relates to the electric field outside the insulator. There is uncertainty about the appropriate equation to express this relationship.

Discussion Status

The conversation is ongoing, with participants sharing insights about the linear nature of the electric field and its values at specific points. There is a lack of consensus on the exact equation needed to describe the electric field inside the insulator.

Contextual Notes

Participants are working within the constraints of a homework problem and are attempting to clarify the relationship between the electric field inside and outside the charged insulator.

Homework Equations



EA = Qenclosed / epsilon

The Attempt at a Solution



I found the electric field outside to be [tex]\rho*d/2\epsilon_{0}[/tex]. Not sure if that helps, I don't know what to do since it says "as a function of x"
 
Physics news on Phys.org
You know it's going to be linear from x = 0 to x = d/2, and at d/2 you know what it is and at 0 it's 0. So ...
 
Hmm i am not sure I follow. I understand its linear from x = 0 to x = d/2 and at d/2 its the same as Eout?
 
That's what it looks like to me.

So what equation expresses that?
