Two electric dipoles of dipole moments $\displaystyle 1.2 \times 10^{-30} \mathrm{Cm}$ and $\displaystyle 2.4 \times 10^{-30} \mathrm{Cm}$ are placed in two different uniform electric fields of strengths $\displaystyle 5 \times 10^4 \mathrm{NC}^{-1}$ and $\displaystyle 15 \times 10^4 \mathrm{NC}^{-1}$ respectively. The ratio of maximum torque experienced by the electric dipoles will be $\displaystyle \frac{1}{x}$. The value of $\displaystyle x$ is \_\_\_\_.
