Particle A of mass `m_A=m/2` moving along the x - axis with velocity `v_0` collides elastically with another particle B at rest having mass `m_B=m/3` . If both particles move along the x - axis after the collision , the change `Deltalamda` in de - Broglie wavelength of particle A , in terms of its de - Broglie wavelength `(lamda_0) ` before collision is :

Options

A. `Deltalamda=5/2lamda_0`
B. `Deltalamda=4lamda_0`
C. `Deltalamda=2lamda_0`
D. `Deltalamda=3/2lamda_0`
