Question

Two identical positive charges $Q$ each are fixed at a distance of '2a' apart from each other. Another point charge $\mathrm{q}_0$ 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 :

Select the correct option:

A

$\sqrt{\frac{4 \pi^3 \varepsilon_0 m a^3}{q_0 Q}}$

B

$\sqrt{\frac{q_0 Q}{4 \pi^3 \varepsilon_0 m a^3}}$

C

$\sqrt{\frac{2 \pi^3 \varepsilon_0 \mathrm{ma}^3}{\mathrm{q}_0 \mathrm{Q}}}$

D

$\sqrt{\frac{8 \pi^3 \varepsilon_0 m a^3}{q_0 Q}}$

✓ Correct! Well done.
