Question

Two particles of masses m_1 ,m_2 move with initial velocities u_1 and u_2. On collision, one of the particles get excited to higher level, after absorbing energy If final velocities of particles be v_1 and v_2, then we must have

Accepted Answer

Correct answer: C. (c) Total initial energy = 12m_1u_1^2+ 12m_2u_2^2 Since, after collision one particle absorb energy . ∴ Total final energy = 12m_1v_1^2+ 12m_2v_1^2+ From conservation of energy, 12m_1u_1^2+ 12m_2u_2^2= 12m_1v_1^2+ 12m_2v_2^2+ ⇒ 12m_1u_1^2+ 12m_2u_2^2- = 12m_1v_1^2+ 12m_2v_2^2

$Two particles of masses m_{1}, m_{2} move with initial velocities u_{1} and u_{2} . On collision, one of the particles get excited to higher level, after absorbing energy ϵ If final velocities of particles be v_{1} and v_{2}, then we must have$
