The figure shows a uniformly charged ring with radius R and total positive charge Q > 0. The ring's central axis coincides with the x-axis and its centre is at x = 0. In the lectures we found that the electric field generated by the ring at points on the x-axis is given by \begin{equation*} \vec{E}(x) = \frac{1}{4\pi\epsilon_0} \frac{Qx}{(x^2 + R^2)^{3/2}}\hat{i}. \end{equation*} Suppose we release a negative point charge with charge $-q < 0$ and mass $m$ from rest at a point $x_0$ close to the ring's centre on the x-axis. By \"close to the ring's centre\" we mean that $|x_0| \ll R$. Show that the charge will undergo approximate simple harmonic motion around the centre of the ring, and determine the frequency with which it will oscillate.
