WebDENSITY AND UPTHRUST The density of a substance is its mass per unit volume. Density = mass/volume ρ =m/v Where ρ (rho) is a Greek letter representing density. Its S.I. unit is kgm -3. WORKED EXAMPLE (1) An object weighs 0.08N in air and 0.01 N in a liquid of density 700kgm -3. Calculate the volume of the solid. SOLUTION ρ =mass/-volume WebAnswer (1 of 6): Upthrust (better known as buoyancy) is equal to weight, but probably not the weight mentioned in this question. Buoyancy is upward force equal to the weight of … WebApr 4, 2024 · Since volume of solid immersed in liquid is equal to the volume of the liquid displaced, We get, upthrust = volume of solid immersed x density of liquid displaced x Acceleration due to gravity upthrust, So, we get upthrust U = V × D × g = 0.2 m 3 × 1 k g m 3 × g = 0.2 g f.
