Question
A proton and a deuteron are accelerated through the same accelerating potential. Which one of the two has less momentum?
Give reasons to justify your answer.
Solution
Momentum
`p=h/lambda`
or `pprop1/lambda`
where, h = plank's constant
As the wavelength of a proton is more than that of deutron thus, the momentum of a proton is lesser than that of deutron. Hence, the momentum of proton is less.
