3. Suppose you have a rock with a mass of 305 g. When attached to a spring scale and lowered completely into water the spring scale reads Fe 2.10 N. Note that this reading is significantly lower than the rock's weight Fo Mg (3 N), because of the buoyant force helping to support it. From this information, calculate the following: (a) Fe: the magnitude of the buoyant force exerted on the rock. Use N2L in conjunction with the FBD shown...

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...
