steta two conditions for floatation of a body
Answers
Answer:
hiii.
how are you??
here is your answer..
Condition for Flotation. An object will float if the buoyancy force exerted on it by the fluid balances its weight, i.e. if FB=mg F B = mg . But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. ... When any boat displaces a weight of water equal to its own weight, it floats.

take care ..
Answer:
CONDITIONS FOR OBJECTS TO FLOAT
I. The average density of the object should be less than the density of the fluid in which the object has to float.Example, a ship is very heavy but it floats because it is hollow inside it contains air, this causes its average density to be lower than that of water.
2.The upthrust force of the fluid on the object must be equal total weight of the object.(law of floatation)
The upthrust force of the fluid on the object must be equal total weight of the object.(law of floatation)Example, a coin will sink to the bottom when placed on the surface of water, this is because the upthrust of water on coin is less than its weight.
Also
3.The volume of object submerged must be large so as to displace large amount of fluid.
hope its help you
