Buoyant force equals ρ g V. If water density is 1000 kg/m³ and V = 0.0001 m³, buoyant force is approximately:

Explanation:
Buoyant force comes from the weight of the fluid displaced by the object, so it equals ρ g V. Here the liquid is water with density 1000 kg/m^3 and the displaced volume is 0.0001 m^3. First find the mass of the displaced water: m = ρ V = 1000 × 0.0001 = 0.1 kg. Then convert that mass to weight: F_b = m g ≈ 0.1 × 9.8 ≈ 0.98 N. So the buoyant force is about 0.98 newtons.
