If I stand at rest on horizontal floor, it pushes upwards on my feet with a force equal to my weight, Mg, where M is my mass. Which of the following is Newton's third-law pair to this upward force on my feet ?
Options:
Answer:
C
Solution:
Newton's third-law pair: the floor pushes up on my feet with the normal force; the force of the same kind that my feet exert on the floor (equal and opposite) is the normal force that my feet exert on the floor. The gravitational force by the Earth on my body is a different interaction, so it is not the pair.
