Questions
A moving sphere P collides another sphere Q at rest. If the collision takes place along the line joining their centres of mass such that their total kinetic energy is conserved and the fraction of K.E transferred by the colliding particle is
detailed solution
Correct option is D
89=4m1m2(m1+m2)2⇒ option verification then fraction of K.E retained is =m1-m22m1+m22= 1-89=19m1+m2m1-m2=31m1;m2=2:1Talk to our academic expert!
