Explanation:

Answer

Key Point : The de-Broglie wavelength of a particle of mass m and moving with velocity v is given by

λ=mvh       (∵p=mv)

de-Broglie wavelength of a proton of mass m1 and kinetic energy k is given by

λ1=2m1kh           (∵p=2mk)

λ1=2m1qVh....(i)        [∵k=qV]

For an alpha particle mass m2 carrying charge q0 is accelerated through potential V, then

λ2=2m2q0Vh

∵ For α−particle  (24He) :  q0=2q and m2=4m1

∴λ2
