(a) Using Eq. 24-32, show that the electric potential at a point on the central axis of a thin ring (of charge q and radius R) and at distance z from the ring is
\(V=\frac{1}{4 \pi \varepsilon_{0}} \frac{q}{\sqrt{z^{2}+R^{2}}}\)
(b) From this result, derive an expression for the electric field magnitude E at points on the ring’s axis; compare your result with the calculation of E in Module 22-4.
