Explanation:
Archimedes' Principle:
- According to Archimedes' Principle, when a body is immersed in a fluid, it experiences an upthrust force equal to the weight of the fluid displaced by the body.
- If this upthrust force is equal to the weight of the body, the body will float in the fluid.
Apparent Weight of a Floating Body:
- When a body floats in a liquid, it displaces an amount of liquid equal to its own weight.
- The apparent weight of the body is the actual weight of the body minus the upthrust force it experiences in the liquid.
- Since the upthrust force is equal to the weight of the liquid displaced (which is equal to the weight of the body), the apparent weight of the body in a liquid is zero.
Conclusion:
- Therefore, when a body floats in a liquid, its apparent weight is zero.
- This means that the body seems to weigh nothing while floating in the liquid, even though its actual weight is still present.
