# Problem: Suppose someone is standing on a scale.  (a) Draw a free body diagram of the forces acting on the person (b) List what the scale would read if the person had a mass of 50 kg. Assume the units of the scale are N. (c) Do the normal force from the scale and the weight of the person form an action/reaction pair, as defined by Newton's third law?
