**Buoyancy or Force of Buoyancy:**

Buoyancy or Force of Buoyancy is the difference of weight of body in air and weight of body in any liquid.

It is Expressed as F_{B.}

F_{B=}W_{a}-W_{L}

Where

W_{a }is the weight of body in air.

W_{L }is the weight of body in any liquid.

**Conditions of Stability for floating bodies**

There are three conditions of stability for floating bodies.

If W>F_{B}

Then the body will sink.

If W<F_{B}

Then the body will float.

And If W=F_{B}

Then the body will partially sink and partially float. The last condition will happen when the density of body and that of liquid are equal or same.

**Note:**W is the weight of the body and F_{B}is the force of buoyancy.
