Figure shows variation of Coulomb force (F) acting between two point charges with $\displaystyle \frac{1}{r^{2}}, r$ being the separation between the two charges $\displaystyle \left(\mathrm{q}_{1}, \mathrm{q}_{2}\right)$ and $\displaystyle \left(\mathrm{q}_{2}, \mathrm{q}_{3}\right)$. If $\displaystyle \mathrm{q}_{2}$ is positive and least in magnitude, then the magnitudes of $\displaystyle \mathrm{q}_{1}, \mathrm{q}_{2}$ and $\displaystyle \mathrm{q}_{3}$ are such that
