In a general debate on topic "normal reaction and mg never form action and reaction pair" a number
of students took part :-
(I) Navneet said – Action and reaction forces should be of same nature
(II) Anand said - Action and reaction forces act on two different bodies here, normal reaction and mg both are acting on the block.
(III) Meenakshi said – Action and Reaction forces balance each other. So, normal reaction and mg should be action and reaction pair.
Mark correct option as your judgement Both (I) & (II) are correct
Solution:
The correct option is:
(II) Anand is correct.
Explanation:
Action and reaction forces act on two different bodies, as per Newton's third law. Normal reaction and gravitational force (mg) both act on the same block, so they cannot form an action-reaction pair.
