A particle of mass 3 m at rest decay Into two particles of masses m and 2m having non-zero velocities. What is the ratio of the de-Broglie wavelengths of the particle `(lambda_(1)//lambda_(2))`.
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`
