Question 1
What does Archimedes' principle describe?
- Buoyant force equals weight of displaced fluid
- Weight equals mass times gravity
- Pressure equals force divided by area
💡 Hint: Think about floating objects in fluid.
Question 2
True or False: A metacenter is where buoyant force acts when the object is tilted.
- True
- False
💡 Hint: Recall the earlier discussion about buoyancy.

Challenge Problems
Push your limits with challenges.
Question 1
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.
Question 2
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.
