The meterstick shown is 100 cm long. It is free to pivot around its center of gravity (CG), which is at the 50 cm mark. There is a 25.0 N block hanging from the 80 cm mark. Decide where each of the other blocks should be placed, one at a time, to balance out the 25.0 N block. At what mark on the meter stick would you place a 18.0 N block to balance the 25.0 N block? At what mark on the meter stick would you place a 43.0 N block to balance the 25.0 N block
