Atotal charge q is uniformly distributed on a ring of radius r in the xey plane centered on the origin. (a) calculate the electric field and potential at the center of the ring (b) consider a particle of mass m and charge -q constrained to slide along the z-axis. show that the charge will execute simple harmonic motion for small displacements about the origin and calculate the frequency of oscillation
