Now imagine a set up as shown below: =\\ Page | 4 Middlesex County College a) The 10 kg mass is placed on a plank at 1.5 m from the fulcrum. (Note: Take each marking on the plank is 0.25 m apart). What would the spring scale read if the plank is in static equilibrium? (The plank is of negligible mass). SHOW WORK b) What would be the spring scale reading in part a) if the mass of the plank 1s 5 kg? (Note: Take each marking on the ruler is 0.25 m apart). SHOW WORK
