A proton and deutron are accelerated through the same accelerating potential. Which one of the two has (a) greater value of de-broglie wavelength associated with it, and (b) less momentum? Give reasons to justify your answer.

Explanation

(a) De-Brogie wavekebgtgm `lambda prop1` mass (for same accelerating potential). Mass of a protential). Mass of a proton is less as compared to a duteron. So, it will have greater value of deuteron is more as compared to a deuteron. So, it will have greater value of momentum.
