A particle of mass 5M at rest decays into two particle of masses 2 m and 3 m having non zero velocities. The ratio of de - broglie wavelengh of the particles is

A

`3//2`

B

`2//3`

C

`1//3`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
4
According to law of conservation of linear momentum, the particles will have equal and opposite momentum. The de-Broglie wavelenght is given by `lambda=(h)/(p)` , so `(lambda_(1))/(lambda_(2))=1`.
