Challenge Problems

A rectangular box is submerged in water. If the box dimensions are 2m x 1m x 1m, with a density of 500 kg/m³, calculate the buoyant force acting on the box.
💡 Hint: Use the formula: Buoyant Force = Density of Fluid * Volume Displaced * g.
A floating object is observed to have its center of gravity and metacenter coinciding. What type of equilibrium is this, and what does it imply about the object's stability?
💡 Hint: Consider the implications when buoyancy and weight act through the same point.
