A proton and a triton are accelerated from rest through a potential V. The ratio of their de Broglie wavelength is:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → $\sqrt{3}$ : 1
de-Broglie wavelength of a charge moving in a electric field
$\lambda=\frac{h}{\sqrt{2 m q V}}$
Mass of triton = 3 (mass of proton)
$\frac{\lambda_1}{\lambda_2}=\sqrt{3}: 1$
