Question 1
What does Archimedes' Principle state?
- A submerged object experiences a downward force.
- A submerged object experiences an upward buoyant force equal to the fluid displaced.
- Buoyant force increases with depth only.
💡 Hint: Think about submerged objects in water.
Question 2
True or False: The stability of an object is improved when the center of gravity is above the center of buoyancy.
- True
- False
💡 Hint: Relation of CG and CB is key in stability.
