For the blocks in Problem 50, assume they are barely submerged in water so that block 1

Question:

For the blocks in Problem 50, assume they are barely submerged in water so that block 1 is just below the surface. If block 2 has a density twice that of block 1, what is the density of block 2?

Data from problem 50

Two metal blocks are attached by a cable as shown in Figure P10.50 and are submerged at rest near the surface of a lake. If the volumes are V₁ = 2.0 m³ and V₂ = 1.2 m³, what is the total buoyant force on the two blocks??
