Spring Scale

A beaker of mass 1 kg contains 2 kg of water and rests on a scale. A 2kg block of aluminum (specific gravity 2.70) suspended from a spring scale is suspended from a spring scale is submerged in water, as shown in figure. Find the readings of both scales.

A rock is found to weigh w in air when suspended from a spring scale. When completely submerged in water while attached to the spring scale, it weighs w_("submerged") as shown in Fig. Find the density of the rock rho_("rock") in terms of Rock the scale reading and the density of water
