A particle of mass M at rest decays into two particles of masses `m_1` and `m_2` havibng non zero eloctities.What is the ratio of the de-Bronglie waveelngths of the two particles?

What is the direction of gravitational force betwen two particles?

A particles A with mass m_A is moving with velocity v and hits a particle B (mass m_B) at rest (one dimensional motion) find change in the de-Broglie wavelength of the particle A. Treat the collision as elastic.
