Three masses are attached to a uniform meter stick, as shown in Figure 12.9. The mass of the meter stick is 150.0 g and the masses to the left of the fulcrum are m2=50.0g and m2=75.0g. Find the
mass më that balances the system when it is attached at the right end of the stick, and the normal
reaction force at the fulcrum when the system is balanced.
