What should be the order of arrangement of de-Broglie wavelength of electron `(lamda_(e))`, an `alpha-` particle `(lamda_(alpha))` and proton `(lamda_(p))` given that all have the same kinetic energy ?

A

`lamda_(e)=lamda_(p)=lamda_(alpha)`

B

`lamda_(e)ltlamda_(p)ltlamda_(alpha)`

C

`lamda_(e)gtlamda_(p)gtlamda_(alpha)`

D

`lamda_(e)=lamda_(p)gtlamda_(alpha)`
