What does Archimedes’ Principle state?
💡 Hint: Think about what happens when an object is placed in a fluid.

Challenge Problems
Push your limits with advanced challenges
An object weighs 200 N in air. When submerged in water, it exerts a buoyant force that changes its apparent weight. What is the apparent weight of the object if it displaces 0.1 m³ of water? (Density of water = 1000 kg/m³)
💡 Hint: Use the weight of the water displaced to find the buoyant force.
A cubic block of material has sides of 0.5 m and a density of 800 kg/m³. Will it float or sink when placed in water?
💡 Hint: Compare the weight of the block against the buoyant force to determine the outcome.
