A proton (11p^1_1\text{p}11p) and an alpha particle (24He2+^4_2\text{He}^{2+}24He2+) are accelerated from rest through the same potential difference VVV.
What is the ratio de Broglie wavelength of the protonde Broglie wavelength of the alpha particle\displaystyle \frac{\text{de Broglie wavelength of the proton}}{\text{de Broglie wavelength of the alpha particle}}de Broglie wavelength of the alpha particlede Broglie wavelength of the proton?
