If a projectile explods in mid air then just before and just after explosion, choose correct option(s)

Projectile Explodes In Air

Assertion: If a projectile explodes in mid air, then no external force acts on the projectile during explosions. Reason: Center of mass in this case follows the same path.

A canon shell explodes in mid air, its total

Two projectiles collide in air, then for just after and before the collision

Two projectiles collide in air, then for just after and before the collision

STATEMENT-1 : When a projectile explodes in mid air the centre of mass follows circular path after explosion. STATEMENT-2 : In an elastic collision velocities can't be interchanged it colliding bodies have different masses. STATEMENT-3 : During a perfectly elastic collision the kinetic energy of the system remains constant.
