Calculating Electric Field at a Point from Multiple Charges

Click For Summary

Homework Help Overview

The discussion revolves around calculating the electric field at a specific point due to multiple point charges, specifically two charges with different magnitudes and positions in three-dimensional space. Participants are exploring the application of the superposition principle and vector calculations in this context.

Discussion Character

  • Exploratory, Mathematical reasoning, Assumption checking

Approaches and Questions Raised

  • Participants discuss the use of vector calculations for electric fields, questioning their methods and the correctness of their calculations. There are attempts to clarify the use of unit vectors and the correct formulation of the electric field equations. Some participants express confusion about the variables involved and the expected form of the answer.

Discussion Status

The discussion is active, with participants sharing their calculations and questioning each other's approaches. Some guidance has been offered regarding the simplification of expressions and the handling of vector components. There is a recognition of the complexity involved in the calculations, and participants are exploring different interpretations of the problem.

Contextual Notes

Participants are working under the constraints of homework rules, which may limit the amount of direct assistance they can provide to one another. There are also indications of potential misunderstandings regarding the setup of the problem and the assumptions made in their calculations.

You should be using z^2 + x^2... L should only be in the limits of your integral...

Is E_z the only answer given in the back?

yes the only answer, this is what needed i guess.

Why do you ask? is it wrong?

No, well that's the z-component... that doesn't include the other component... maybe I misunderstood the problem somehow... or maybe they left out that component... not sure...

Did they ask for the total field at (0,0,z), or just the z-component of the field at (0,0,z) ?

Sorry, just the Z.

Thanks, I got it :) .
