Question 9 1F You are performing an experiment on rotational equilibrium. You place a 50 gram mass a distance of 12.5cm on beam of very low [negligible] mass as shown in the image below. A second mass is placed a distance of 6.25 cm to the right of the fulcrum or pivot point (also shown in the image). What is this second mass? Please give your answer in units of grams, however, do not explicitly include units when typing your answer into the answer box.
