Homework Statement


Sketch a field line picture for a circular arc with a uniform linear charge density.


Homework Equations





The Attempt at a Solution


To do this do I just break up each segment on the arc into small segments each of charge dQ and draw the field line along the electric field caused by each small segment? If so, assuming the charge is positive, on the "outside" of the arc does the field spread out pointing away from the arc, and on the inside does it seem to focus to almost a point (still pointing in direction away from arc)?
Thanks

Do you want the field lines in 3D or just in the plane of the arc?
