Torque

The meterstick shown to the right 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 16.0-N block to balance the 25.0-N block?
