[QUOTE="ChiralSuperfields, post: 6850407, member: 731016"] [B]Homework Statement:[/B] Please see below [B]Relevant Equations:[/B] Please see below For A.1 of this problem, [ATTACH type="full" alt="1675405830601.png"]321658[/ATTACH] The solution is [ATTACH type="full" alt="1675399497646.png"]321657[/ATTACH] However, I have a doubt about the linear charge density ##\lambda##. I don't understand how ##\lambda = \frac {q}{2\pi R} ## since this is not a thin ring, but has a non-negligible width of ##2a## I think that the toroid has a larger area than thin circle with a circumference ##2\pi R## so linear charge density should be less than that expression. EDIT: How would we calculate the electric potential if the thickness was not neglected? Many thanks !
