Two positive point charges q are held fixed on the x-axis at x=a and x= –a. a third positive point charge q, with mass m, is placed on the x-axis away from the origin at a coordinate x such that /x/< < a. the charge q, which is free to move along the x-axis, is then released. find the frequency of oscillation of the charge q. (hint: when the restoring force is directly proportional to the displacement from equilibrium, the oscillation is called simple harmonic motion. use the binomial expansion \left( {1 + z} \right)^n = 1 + nz + n\left( {n - 1} \right)z^2 /2 + ; ), valid for the case \left| z \right| < 1.) express your answer in terms of the variables q, q, m, a and appropriate constants.
