A metallic sphere of mass 1 kg and volume 2 × 10⁻⁴ m³ is completely immersed in water. The buoyant force exerted by water on the sphere is: (Given : density of water = 1000 kg/m³, g = 10 m/s²)

Two identical solid pieces, one of gold and other of silver, when immersed completely in water exhibit equal weights. When weighed in air (given that density of gold is greater than that of silver)

If two miscible liquids of same volume but different densities ρ₁ and ρ₂ are mixed, then the density of the mixture is given by

Gravitational acceleration at moon is 1/6 of that on earth. On earth, if an object floats in water with fraction 'fe' of its volume submersed in water, and on moon, fraction 'fm' is submersed, then:

The immersed portion of a piece of pure ice floating in water is
