An electron of mass \( m_{e} \) and a proton of mass \( m_{p} \) are
\( \mathrm{P} \)
accelerated through the same potential difference. The ratio of the de Broglie wavelength associated with an electron to that associated with proton is
(1) 1
(2) \( \mathrm{m}_{p} / m_{e} \)
(3) \( \mathrm{m}_{e} / m_{p} \)
(4) \( \sqrt{m_{p} / m_{e}} \)
