Question
What is the law of floatation?
Advertisements
Solution
A body will float in a liquid if the weight of the body is equal to the weight of the liquid displaced by it.
Key Points:
-
Buoyant Force:
- When a body is partially or fully submerged in a liquid, it experiences an upward force called the buoyant force.
-
Condition for Floating:
- For a body to float, the buoyant force must equal the weight of the body.
- This happens when the density of the body is less than or equal to the density of the liquid.
-
Stable Floating:
- In equilibrium, the body displaces an amount of liquid whose weight is exactly equal to its own weight.
