. A meter stick has a pivot that is located at (35 cm). On this meter stick we place 200 g @ 20 cm, 200 g @ 25 cm, 350 g @70 cm and 100 g @80 cm. The meter stick has a mass of 150 g. a. How much mass needs to be placed at 55 cm in order to balance the meter stick.__________________________ b. Where will you put 500 g in order to balance the meter stick?___________________________________   If you could clearly circle the answers I need, that would be great!  Thanks!
