Linear charge density (what equation?)

Click For Summary
SUMMARY

The discussion focuses on calculating the total electric field at point P due to two charged rods, with a resultant magnitude of 190.2 V/m and vector components Ex = -34.23 V/m and Ey = -155.32 V/m. Participants emphasize the importance of vector addition of the electric fields generated by each rod, taking into account the linear charge densities (lambda1 and lambda2). A sketch of the electric field vectors is recommended for clarity, particularly when considering negative charge densities on 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.)
