A Proton and a Deuteron Are Accelerated Through the Same Accelerating Potential. Which One of the Two Has the Greater Value of De-broglie Wavelength Associated with It, and Give Reasons to Justify Your Answe - Physics


A proton and a deuteron are accelerated through the same accelerating potential. Which one of the two has the greater value of de-Broglie wavelength associated with it, and Give reasons to justify your answer.



de-Broglie wavelength of a particle depends upon its mass and charge for same accelerating potential, such that


Mass and charge of a proton are mp and e respectively, and, mass and charge of a deutron are 2mp and e respectively. where, e is the charge of an electron


Thus, de-broglie wavelength associated with proton is`sqrt2` times of the de-broglie wavelength of deutron and hence it is more.

  Is there an error in this question or solution?
