JEE Main Physics question

Statement I: Two particles moving in the same direction do not lose all their energy in a completely inelastic collision. Statement II: Principle of conservation of momentum holds true for all kinds of collisions. [AIEEE 2010]

(A)Statement I is true, Statement II is true, Statement II is the correct explanation of Statement ICorrect
(B)Statement I is true, Statement II is true, Statement II is not the correct explanation of Statement I
(C)Statement I is false, Statement II is true
(D)Statement I is true, Statement II is false

Answer: (A)

Solution

In a completely inelastic collision, the particles move together after impact with a common velocity (given by momentum conservation); since momentum is always conserved and
