Shown below are seven situations where a student is holding a meter stick at the left end. The stick is held with various angles, as indicated. A 1.0 kg mass is hung on the meter sticks at different locations. All of the meter sticks are identical, but the distance along the meter stick where the mass is hung varies, again as indicated in the diagrams. You may ignore the mass of the meter stick itself in this problem. 45 B. 30 Rank these situations, from greatest to least, on the basis of how difficult it would be for the student to hold the meter stick in place as shown. Least Greatest Please carefully explain your reasoning in words. What physics relationship (equation) are you using to determine your ranking?
