Question

Margie, who weighs 543 N, is standing on a bathroom scale that weighs 45 N. (a) With what magnitude force does the scale push up on Margie? (b) What is the interaction partner of that force? (c) With what magnitude force does the floor push up on the scale? (d) Identify the interaction partner of that force.

Answer 1

a) By the third Newton's law, the scale push up on Margie with a force that the same with a force with it Margie press on the scale. So, F = 543 N

b) The floor is the interaction partner of this force.

c) The floor push up on the scale with the force F = 543+45=588 N.

d) Margie is the interaction partner of this force.
