After the explosion which statements below are true?

Question

An object initially at rest explodes

I. Momentum is conserved

II. Velocity is conserved

III. The masses of fragments are equal

IV. The momentum of the system is zero

A. I and III

B. I, II, and III

C. I and IV

D. I, III, and IV

Answer 1

Option C is correct

In case of Inelastic system , Momentum is conserved.

As initial momentum is zero , final momentum will also be zero.

Fragments can be of different masses after explosion , but total mass remains the same
