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?

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

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

so we have

so from above relation we can say that

i) then it will sink inside water

ii) 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

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
