A particle of mass 3m at rest decays into two particles of masses m and 2m having non-zero volocities. The ratio of the de-Broglie wavelength of the particles `(lambda_(1)/(lambda_(2)))` is

A

`(1)/(2)`

B

`(1)/(4)`

C

`2`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
D
From conservation of linear momentum, both the particles will have equal and opposite momentum. The de Broglie wavelength is given by
`lamda=(h)/(p)implies(lamda_1)/(lamda_2)=1`
