Potential At A Point Near A Charged Ring (Solved Problem)

In this episode we basically apply the concept of integration to determine the electric potential V at a point P which is along the ring axis. The charge Q is uniformly distributed on the ring and we divide the ring into infinitesimal segments dq and integrate dq/r. But since all these segments have the same distance r from point P, the factor 1/r is taken outside the integral, thus simplifying the equation V = 1/4πϵo ∫ dq/r into V = Q/4πϵo (√x2 + a2) or in terms of the electrostatic constant, we replace 1/4πϵo by k and so V = kQ/(√x2 + a2). This equation is used to determine the target variables in the problem.    / @sirk_ice   The background music used in this video is courtesy of: Music track: Heaven by Aylex
