Two identical positive charges Q each are fixed at a distance of '2a' apart from each other. Another point charge $\displaystyle q_0$ with mass ' $\displaystyle m$ ' is placed at midpoint between two fixed charges. For a small displacement along the line joining the fixed charges, the charge $\displaystyle q_0$ executes SHM. The time period of oscillation of charge $\displaystyle q_0$ will be :
Official answer
(1)
$\displaystyle \sqrt{\frac{4 \pi^3 \varepsilon_0 m a^3}{q_0 Q}}$
