An object suspended from a spring scale weighs 0.56 N in air. The same object completely submerged in water and suspended from the same spring scale weighs 0. P(water) = 1 g/ml = 1 g/cm^3 = 1000 kg/m^3 Draw a clearly labeled free body diagram for: i. The mass suspended from the spring balance in air ii. The mass suspended from the the spring balance in water

4. When a solid object is suspended from a spring scale in air the scale reads 21.7N. The object is then completely submerged in water and the spring scale reads 16.6N. Draw a free-body diagram for the object suspended from the scale in air. You may ignore the very small buoyant force from the air. Using a Newton's 2 nd law equation for the vertical direction on your FBD determine the mass of the object. Draw a free-body diagram for...
