- Apparent Weight = Actual Weight - Buoyant Force. - Actual Weight = Weight of water inside + Weight of balloon = (Volume of water × Density of water × g) + 0 = (200 cm³ × 1 g/cm³) × g = 200 g × g = 0.2 kg × g. - Buoyant Force = Weight of displaced fluid = Volume of displaced fluid × Density of fluid × g. - Volume of displaced fluid = Volume of submerged object = Volume of balloon filled with water = 200 cm³ = 0.0002 m³. - Density of water = 1000 kg/m³. - Buoyant Force = (0.0002 m³ × 1000 kg/m³) × g = 0.2 kg × g. - Apparent Weight
A weightless rubber balloon is filled with 200 cc of water. Its weight in water is equal to:
