A particle of mass 4m at rest decays into two particles of masses m and 3m having non-zero velocities. The ratio of the de Broglie wavelengths of the particles 1 and 2 isA. `(1)/(2)`B. `(1)/(4)`C. 2D. 1

Answer» Correct Answer - D
(d) : According to law of conservation of linear momentum.
The de Broglie wavelength is given by
`lamda=(h)/(p)" ":." "(lamda_(1))/(lamda_(2))=1`
