Matter waves (DC Broglie waves)

Question

A particle of mass 3m at rest decays into two particles of masses m and 2m having non-zero velocities. The ratio of the de Broglie wavelengths of the particles ( $\frac{λ_{1}}{λ_{2}}$ ) is

Moderate

A

½
B

¼
C

2
D

none of these

Solution

From the law of conservation of momentum $P_{1} = P_{2}$ (in opposite direction)
Now the de-Broglie wavelength is given by $λ = \frac{h}{p}$ .So we can write the required ratio will be equal to 1
