Answer 2

Explanation:

= constant

Le In the absence of external force, total momentum of system remains constant. Let us have an isolated system of two bodies

of masses m, and m. Let É, be the force exerted 12 by , on me, which is action and bethe force werted by my on m, which is reaction.

Let, due to F the rate of change of 12

momentum of m, be

due to force 21

and that of my be

and Fa

New, Fia+ Fan

where is the total momentum of system. Since according to second law of motion, in the absence of external force, total momentum of system remains conserved,

Hence third law of motion.
