A fulcrum is placed under a meter stick at its center of mass at 40 cm. This is the place where the meter stick pivots. A 150 g mass is clamped at the 10 cm mark. An unknown mass is clamped at the 50 cm mark and the system is in equilibrium. Ignoring the mass of the clamps, what is the unknown mass?
