You are part of a design team assigned the task of making an electronic oscillator that will be the timing mechanism of a micro-machine. You start by trying to understand a simple model consisting ofan electron moving along an axis through the center and perpendicular to the plane of a thin positively charged ring. You need to determine how the oscillation frequency of the electron depends on the size and charge of the ring for displacements of the electron from the center of the ring which are small compared to the size of the ring. A team member suggests that you first determine the acceleration of the electron along the axis as a function of the size and charge of the ring and then use that expression to determine the oscillation frequency of the electron for small oscillations. xpress your answer for the oscillation frequency in terms of the mass (m) and charge (e) of the electron, the charge (q) and radius (r) of the ring, and Coulomb's constant (k). (All letters are lowercase, remember that "e" is a positive constant.)
