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
Neet 2015 | W.P.E Q 4 |In this
qus what all matters is your perception about collision from given info. Since
it is mentioned that after absorbing energy one of the particle is excited , it
means in other words there will be a loss of kinetic energy during collision.
That’s why , only after absorbing given energy particle, it can be excited to
higher level . Even it’s a single line qus but that can be thought only when we
look at the words carefully. It’s a smart qus.
