The center of gravity of the meter stick is 49 cm. mass of meter
stick 50 g . mass of hanger #1 =5 g. mass of hanger #2 = 5 g.
1.Place the fulcrum at 51 cm. Attach a 200 g mass, plus hanger
#1, at 17 cm on the meter stick and calculate where to attach a 200
g mass, plus hanger #2, to balance it.
2.Balance the stick with the fulcrum at its center of gravity.
