Question : It is difficult to fix a nail on a free-suspended wooden frame. Which law supports this statement?
Option 1: Law of inertia
Option 2: Newton's second law
Option 3: Newton's third law
Option 4: Pascal's law
Correct Answer: Newton's third law
Solution : The correct option is Newton's third law.
When a hammer is used to drive a nail into a wooden block that is not resting against a support, both the block and the nail advance. However, if the block is tightly pressed up against a support when the nail is struck, the support also reacts in kind, driving the nail deeper into the block.
