Question

A particle of charge e and mass m is located at the midpoint of the line joining two fixed collinear dipoles with unit charges as shown in figure. (The particle is constrained to move only along the line joining the dipoles. ) Assuming that the length of the dipoles is much shorter than their separation, the natural frequency of oscillation of the particle is – (June)
