Newton's law
In Newtow third law it is told that" every action has equal and opposite reaction" fine!!! And they will not act on same body otherwise resultant become zero and body will not move. But how in example like for rocket both action (thruster force) and reaction (upward motion) occurred in same body???

Action reaction always acts on different bodies. here in this question, Rocket and it's exhausted fuel are two different bodies. action reaction acts on them. I have attached a demonstration. Best regards.

I think you have some misconception. For rocket action and reaction are not in same direction. Considering the upward motion,rocket exhaust gas with some force towards down. It is the action force and the gas gives gives reaction force on rocket towards up. Suppose you are on space and you have a ball on your hand.Now you want to go upward.what will you do? You can throw the ball with some force towards down(acton).The ball will exert same force on you towards up (reaction) and you will start moving towards up.

Newton's third law always acts on different bodies, in case of rocket too, action and reaction on different objects, rocket and exhausted fuels are different bodies..
