Question

What is the law of floatation?

Answer 1

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:

1. Buoyant Force:

   • When a body is partially or fully submerged in a liquid, it experiences an upward force called the buoyant force.

2. 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.

3. Stable Floating:

   • In equilibrium, the body displaces an amount of liquid whose weight is exactly equal to its own weight.
