A proton and a $\displaystyle \mathrm{Li}^{3+}$ nucleus are accelerated by the same potential. If $\displaystyle \lambda_{\mathrm{Li}}$ and $\displaystyle \lambda_{\mathrm{p}}$ denote the de Broglie wavelengths of $\displaystyle \mathrm{Li}^{3+}$ and proton respectively, then the value of $\displaystyle \frac{\lambda_{\mathrm{Li}}}{\lambda_{\mathrm{p}}}$ is $\displaystyle x \times 10^{-1}$. The value of $\displaystyle x$ is \_\_\_\_. (Rounded off to the nearest integer) [Mass of $\displaystyle \mathrm{Li}^{3+}=8.3$ mass of proton]
