Question 1

What does Archimedes’ Principle state?

  • Buoyant force is always equal to the weight of the object.
  • Buoyant force is equal to the weight of the fluid displaced.
  • Buoyant force is independent of fluid density.

💡 Hint: Think about what happens when an object is placed in a fluid.

Question 2

True or False: An object will float if its weight is less than the buoyant force acting on it.

  • True
  • False

💡 Hint: Consider the balance between weight and buoyant force.

Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
