Question

a cube of side 5 cm is immersed in water and then in saturated salt solution. in which case will it experience a greater buoyant forces

Answer 1

its is simple that the cube will face more buoyant force in salt solution.... it is like that...
now we know that if we will put that cube in simple water then it will only face the buoyant force exerted on it by water..
but when we will put it in salt solution then by adding salt to this water its density will be increased then the simple water.. so the force exerted by the water will also get increased....
so that's how the buoyant force exerted by salt solution on the 5 cm cube will be more than the simple water...
