A proton and an a-particle are accelerated through the same potential. Which one of the two has
(i) greater value of de-Broglie wavelength associated with it and
(ii) less kinetic energy?
Give reasons to justify your answer.


#2

(i) The de-Broglie wavelength of a panicle depends upon its mass and charge per same accelerating
potential, such that,
