Calculate the buoyant force on a 10 kg object submerged in water (density = 1000 kg/m³).
💡 Hint: Use the formula for buoyancy: Buoyant force = density * volume * g.
An object has a center of gravity below its metacenter. Discuss the implications for its stability in water.
💡 Hint: Think about how the forces interact when disturbed.
