# An  equal arm balance is made by placing a meter stick at its center so it looks like a seesaw. The first mass m=3 kg is hung at r= 0.25 m To the left of the center. A second mass equaling 1.4 kg is hung at 0.4 m to the right of the center. At what location with respect to the center of the meter stick must a third mass of 0.8 kg be hung for the meter stick to be in equilibrium? to the left of the center. A second mass equaling 1.4 kg is hung at 0.4 m to the right of the center. At what location with respect to the center of the meter stick must a third mass of 0.8 kg be hung for the meter stick to be in equilibrium? (All angles are 90 degrees)
