JEE Main 2021 · 24 Feb · Shift 1, Chemistry question 53

A proton and a Li$^{3+}$ nucleus are accelerated by the same potential. If λ$_{Li}$ and λ$_p$ denote the de Broglie wavelengths of Li$^{3+}$ and proton respectively, then the value of $\dfrac{\lambda_{Li}}{\lambda_p}$ is $x\times10^{-1}$. The value of $x$ is _______. (Rounded off to the nearest integer)

[Mass of Li$^{3+}$ = 8.3 mass of proton]
