Principle of floatation:
1. The floatation principle states that when an object floats in a liquid, the buoyant force acting on the object is equal to the object's weight.
2.The volume of fluid displaced equals the volume of the object immersed in the fluid.
3. If the object's weight exceeds the upthrust, the object will sink in the fluid.
4. If the weight of the object equals the upthrust, it floats being immersed.
