(adsbygoogle = window.adsbygoogle || []).push({}); 1. Find the work required to move a point charge from infinitely far away to the center of a thin ring.

The point charge is q= 1nanocoulomb.

The rings charge is Q= 2 nanoC.

The ring has a radius r=2m.

2. Relevant equations

U= qV

W= -U

Thoughts

I think the first thing to consider is the field E created by the ring. I also know that this problem should be able to be solved with a single integral.

I don't really know where to start.

Thanks in advance
