Two objects, labeled A and B, are the same size. Object A has a density of 1.21 g/cm3. Object B has a density of 1.37 g/cm3. Both are placed in a beaker of water. Which will float higher in the water?

Neither object will float in water. 

They both have densities greater than 1.0 g/cm³,
so both will sink to the bottom of the beaker.

Like rocks.

Answer:

None of the object float in water

Explanation:

When an object float in water than we can say that buoyancy force due to water will counter balance the weight of the object

As we can say that

[tex]W_g = F_b[/tex]

so here if object is just floating or we can say that if object is in the state of sinking then we have

[tex]\rho_{object} V g = \rho_{water} Vg[/tex]

so we have

[tex]\rho_{object} = \rho_{water}[/tex]

so from above relation we can say that

i)[tex]\rho_{object} > \rho_{water}[/tex] then it will sink inside water

ii)[tex]\rho_{object} < \rho_{water}[/tex] then it will float in water

since we know density of water is 1 gm/cm^3 so here given both objects are having density more than this

so both the objects will sink inside water
