Two charged particles $\displaystyle \mathrm{P}$ and $\displaystyle \mathrm{Q}$, having the same charge but different masses $\displaystyle \mathrm{m}_{\mathrm{P}}$ and $\displaystyle \mathrm{m}_{\mathrm{Q}}$, start from rest and travel equal distances in a uniform electric field $\displaystyle \overrightarrow{\mathrm{E}}$ in time $\displaystyle \mathrm{t}_{\mathrm{P}}$ and $\displaystyle \mathrm{t}_{\mathrm{Q}}$ respectively. Neglecting the effect of gravity, the ratio $\displaystyle \left(\frac{\mathrm{t}_{\mathrm{P}}}{\mathrm{t}_{\mathrm{Q}}}\right)$ is :
