Two identical positive charges Q each are fixed at a distance of '2a' apart from each other. Another point charge q 0 with mass 'm' is placed at midpoint between two fixed charges. For a small displacement along the line joining the fixed charges, the charge q 0 executes SHM. The time period of oscillation of charge q 0 will be:
