5. Three masses are attached to a uniform meter stick, as shown in (Figure). The mass of the meter stick is 150.0g and the masses to the left of the fulcrum are m1=50.0gm and m2=75.0g.Find the mass m3 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.
