If proton, electron and a-particle are moving with same kinetic energy then the order of their de-broglie's wavelength.
Text Solution
Verified by ExpertsThe correct answer is:
B
We know that de-broglie's wavelength is given by
if 
same then 
the order of mass of electron, proton and alpha particle is 
hence, order of de-broglie's wavelength is
