An electron and a proton are accelerated through the same potential. If their masses are $m_{e}$ and $m_{p}$ respectively, then the ratio of their de Broglie wavelengths is:

Options:

Answer:

Solution:

Same $V$ and same charge magnitude: $λ \propto \frac{1}{m}$ , so $\frac{λ _{e}}{λ _{p}} = \frac{m _{p}}{m _{e}}$ .
