Matter Waves: de Broglie Wavelength question from JEE Main 2026 (4 Apr, Shift 2)

The de Broglie wavelength associated with an electron accelerated through a potential difference V is $\lambda_\mathrm{e}$ and the de Broglie wavelength associated with a proton accelerated through the same potential difference is $\lambda_\mathrm{p}$. If their corresponding masses are $m_\mathrm{e}$ and $m_\mathrm{p}$, respectively, then the ratio of their de Broglie wavelengths $\left(\frac{\lambda_e}{\lambda_p}\right)$ is ______.
