De Broglie poroposed that moving micro particles exhibit wave behaviours. Electron in a Bohr.s orbit also shows dual nature whose wave length is given by `lambda_(e) = (h)/(m_(e)V_(e))`
`m_(e)` = mass of electron , `V_(e)` = velocity of electron , h = planck.s constant
Bohr.s atomic model is in good agreement with De-broglie concept and the electron has fixed energy in Bohr.s orbit : `2pi r = n lambda` (constructive wave in phase).
Two moving micro particles possess their kinetic energies in 2:1 ratio with same De-Broglie.s wave length.s What is the ratio of their masses?

A

`1:1`

B

`1:2`

C

`4:9`

D

`1:4`
