MCQ
A completely inelastic collision is one in which the two colliding particles
  • A
    Are separated after collision
  • Remain together after collision
  • C
    Split into small fragments flying in all directions
  • D
    None of the above

Answer

Correct option: B.
Remain together after collision
b
(b) Completely inelastic collision is one in which the coefficient of restitution is zero.

Coefficient of restitution means the speed of separation of particles is zero.

Thus the two particles remain together after collision.
