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

1:1

B

1:2

C

3:2

D

2:1

Text Solution

Verified by Experts

The correct Answer is:
A
From conservation of linear momentum both the particles will have equal and opposite momentum. The de-Broglie wavelength is given by
`lambda=h//p`     `therefore`  `lambda_(1)//lambda_(2)=1`
