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.

 
  Is there an error in this question or solution?
