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