Ram and Shyam were sitting in a restaurant and try to push a pillar with all their might. Ram explains the situation that the pillar did not move because of its inertia, while Shyam says that it is because of action and reaction forces cancel each other’s effect.
Read the above passage and answer the following questions:

  1. Which of the two friends give correct justification?
  2. Compare the values of Ram and Shyam.
  3. If Newton’s third law holds goods, then why do not action and reaction forces cancel each other, when we walk?

  1. Ram gives the correct justification.
  2. Both Ram and Shyam are experimental and keen observer. They possess a curiosity to learn and try to discuss the facts.
  3. 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.
