# Positive charge knows how to dance !

Two equal negative point charges each having magnitude q are fixed at $$(0,a),(0,-a)$$ respectively. A uniform positive point charge $$Q$$ is released from rest from point $$(x,0)$$ where $$x$$ Is very very small as compared to $$a$$. Then positive charge performs simple harmonic motion, then find the time period of this S.H.M.

If the answer can be represented in this form

$T= \sqrt{\frac{b\pi^3 m\epsilon_{0}a^3}{Qq}}$

Then find the value of $$b$$.
