Question

two boys are sitting in a restaurant and try to push a pillar with all their might. The first boy explains the situation that the pillar did not move because of its inertia, while the second one says that it is because action and reaction forces cancel each others effect. a) which of the two boys give correct justification? b) compare the values of both the boys. c) If Newton's third law holds good why don't action and reaction forces cancel each other when we walk?​

Answer 1

the the first one gives the correct answer both the friends are experimental and keen observer they have a curiosity to find things and know the facts both forces acts on different bodies

I hope it helps

Answer 2

Answer:

Ram gives the correct justification.

Both Ram and Shyam are experimental and keen observer. They possess a curiosity to learn and try to discuss the facts.

Both forces act on different bodies. During walking, a person pushes the ground in backward direction and in the reaction, the ground also pushes the person with equal magnitude of force but in opposite direction, This unables action and reaction forces cancel each other.
