Oscillating on a line **
Two positive point charges Q are located at points (±R, 0). A par- ticle with positive charge q and mass m is initially located midway between them and is then given a tiny kick. If it is constrained to move along the line joining the two charges Q, show that it under- goes simple harmonic motion (for small oscillations), and find the frequency.
