What is the buoyant force on an object weighing 20 N that displaces 16×10^(−6) m^3 of ethyl alcohol? (density of ethyl alcohol = 0.806 x 10^3 kg/m^3)​

Calculating the buoyant force

Given

  • Fluid Density (ρ) = 0.806 x 10³ kg/m³
  • Displaced Volume (V) = 1.6 x 10⁻⁶ kg/m³
  • Acceleration due to Gravity (g) = 9.8 m/s²
  • Buoyant Force (B) = ?

Use the Archimedes Principle to calculate the buoyant force.

B = ρVg

B = (0.806 x 10³ kg/m³)(1.6 x 10⁻⁶ kg/m³)(9.8 m/s²)

B = 0.01263808 N
