For a ring of charge centered about the origin, how would you calculate the charge experienced by a point within the ring of charge but not at the center?(adsbygoogle = window.adsbygoogle || []).push({});

So, I know for a ring of charge dE_x = kdq / r^2 = (k*lambda*ds) / r^2 where ds is the arc length.

Then what do I integrate over?

And does the fact that the point isn't at the center/origin, important?

I'm guessing I need to solve that integral, then determine q.
