Electrostatics question

2022 · 27 Jul · Shift 1 · Q56

JEE MainPhysicsElectrostaticsMCQ+4 / −1
Two identical positive charges QQQ each are fixed at a distance of '2a' apart from each other. Another point charge q0q_{0}q0​ with mass 'm' is placed at midpoint between two fixed charges. For a small displacement along the line joining the fixed charges, the charge q0\mathrm{q}_{0}q0​ executes SHM\mathrm{SHM}SHM. The time period of oscillation of charge q0\mathrm{q}_{0}q0​ will be :
