A partical of mass M at rest decays into two Particles of masses `m_1

1.	A partical of mass M at rest decays into two Particles of masses `m_1 and m_2` having non-zero velocities. The ratio of the de - Broglie wavelengths of the particles `lambda_1\| lambda_2` is (a) `m_1//m_2` (b)`m_2// m_1` (c ) 1 (d)`sqrt2 // sqrt1`A. `(m_2)/(m_1)`B. `(m_1)/(m_2)`C. `(sqrtm_1)/(sqrtm_2)`D. `1:1`
Answer» Correct Answer - D `lamda=(h)/(mv)` Here, `0xxM=m_1v_1+m_2v_2` Clearly, `m_1v_1=-m_2v_2` In magnitude, mv `=` constant `(lamda_1)/(lamda_2)=(1)/(1)`
