Figure (a) below shows a solid cube hanging from a spring scale, with the scale measuring 5.25 N. In figure (b), the suspended cube is submerged in water, and the scale now reads 3.28 N. What is the density (in kg/m) of the cube? (Hint: the free-body diagram to the right of figure (b) shows the forces acting on the cube, with B and T pointing up and Mg pointing down.) ->> a 3 kg/m Scale BAAT b Mg
