A spring scale A and a lever scale B having equal lever arms are fastened to the roof of an elevator, and identical packages are attached to the scales as shown. Knowing that when the elevator moves downward with an acceleration of 1 m/s2 the spring scale indicates a load of 50 N, determine the load indicated by the spring scale in Newton when the elevator moves upward with an acceleration of 1 m/s2.
