Two particles of masses m1,m2 move with initial velocities u1 and u2. On collision, one of the particles get excited to higher level, after absorbing energy ϵ. If final velocities of particles be v1 and v2 then we must have after absorbing energy ϵ. If final velocities of particles be v1 and v2 then we must have m2 move with initial velocities u1 and u2. On collision one of the particles get excited to higher level Two particles of masses m1 August 28, 2020 Category: Chapter 8 - Collisions , NEET Last 32 Years Solved 1988 - 2019 Physics and Chemistry Video Solutions , Physics , Facebook Messenger WhatsApp Share this:TwitterFacebook Related
