Assertion (A): | When a firecracker (rocket) explodes in mid-air, its fragments fly in such a way that they continue moving in the same path, which the firecracker would have followed, had it not exploded. |
Reason (R): | Explosion of cracker (rocket) occurs due to internal forces only and no external force acts for this explosion. |
