Linear charge density (what equation?)

Click For Summary

Homework Help Overview

The discussion revolves around understanding the electric field produced by two charged rods and the relevant equations involving linear charge density. Participants are exploring how to calculate the total electric field at a specific point due to these rods.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the vector sum of electric fields from each rod and question how to incorporate the linear charge densities into their calculations. There is also a suggestion to visualize the problem through sketches.

Discussion Status

The conversation is ongoing, with some participants providing hints and suggestions for approaching the problem. There is an acknowledgment of confusion regarding the applicability of certain numerical values, and the need for clarification on how to combine the electric fields from each rod.

Contextual Notes

One participant notes that they initially omitted certain numerical values, which they now believe may be relevant. There is also a mention of potentially needing to consider negative charge density for one of the rods.

Hint: The total electric field at P is due to the vector sum of the fields from each rod.
 
magnitude of 190.2 V/m, with components Ex = -34.23 V/m and Ey = -155.32 V/m.

Oh, I didn't include this numbers before...didn't think they were applicable. Sorry, I'm stuck :(

So, E = the above equation for lambda1 + lambda2?
 
Try drawing a sketch of the individual E vectors from each rod at point P. These have to add as vectors to the total E. (You might have to allow for a negative charge density on a rod.)
