Question

A block of metal is submerged in water and experiences an upthrust of 10 N. If the density of the metal is 8000 kg/m³ and the volume of the block is 0.001 m³, calculate the buoyant force acting on the block.

The volume of a 500 g sealed packet is 350 cm³. Will the packet float or sink in a saturated salt solution, if the density of the solution is 1.2 g cm⁻³? What will be the mass of the solution displaced by this packet?

A ball weighing 4 kg of density 4000 kg m⁻³ is completely immersed in water of density 10³ kg m⁻³ Find the force of buoyancy on it. (Given g = 10 m s⁻².)
