Electric charges and fields: Semicircular charge distributions

  1. Apr 24, 2016 #1
    1. The problem statement, all variables and given/known data
    If linear charge density is equal to 1micro coulomb per meter, then what is the electric field intensity at O?
    2. Relevant equations


    3. The attempt at a solution
    The electric fields due to the two straight lines should cancel out.. But how to progress further? Please let me know...

    Finding the fields due to the semi-circles, is it not?

    Ok so... How is it done? Is there any formula or logic behind that?

    That should be your part to find the related formula in the "Relevant equations" section of the template.

    Ok can you please elaborate on how to find it? And how to proceed with the problem?
