The de-Broglie wavelength associated with an electron and a proton were calculated by accelerating them through same potential of $\displaystyle 100$ V . What should nearly be the ratio of their wavelengths $\displaystyle ?\left(\mathrm{~m}_{\mathrm{p}}=1.00727 \mathrm{u} \mathrm{m}_{\mathrm{e}}=0.00055 \mathrm{u}\right)$
Official answer
(1)
$\displaystyle 43$ : $\displaystyle 1$
