Question
A proton, when accelerated through a potential difference of V volts, has a de-broglie wavelength λassociated with it. If an alpha particle is to have the same de-broglie wavelength λ, it must be accelerated through a potential difference of :
Options
A.V/8 volts
B.V/4 volts
C.4 V volts
D.8 V volts
⇒ vα = vP
