Archimedes' Principle

1. Archimedes' Principle states that for a body immersed wholly or partially in a fluid, the buoyant force is equal to the weight of the fluid displace.

2. Buoyant force=weight of fluid displace

3. F=pgv

where F=buoyant force in N

p=density of the liquid 

g=gravitational acceleration

v=volume off liquid displaced

4. For principle of floatation, weight of object=buoyant force.
