We will find the electric field=? of a circular ring or radius=R with a linear charge density (lambda) a perpendicular distance r away from the center of the ring. Ex. 5

If it were a stranger shape instead of a circle, would you take the line integral for dq such that dq=lambda ds where ds would parameterize x and y

[@MichelvanBiezen]

You would need to define a function describing the shape and integrate over that function,

[@famlit.]

@@MichelvanBiezen it’d be interesting to find the electric field of a parabola but I’d imagine that the integration would be too time consuming. Probably why I have only seen electric fields for simpler shapes
