Thin Ring Electric Field (10:32)
The electric field along the axis of a thin ring is determine using integrals and Coulomb’s Law. We prove that if the point is far enough away, the ring acts like a point charge. We prove that a charge place near the center of the ring will oscillate in simple harmonic motion.
