1.	A body of mass 50 kg has a volume of 0.049 m3 . The buoyant force on it is?
Answer» Since the net upward force must be equal to the net downward force. So, buoyant force = mg=50x9.8=49kgf<br>Can you see the answer again. Is it 49kg f?<br>Sorry sis but in the book it is given the option with the answer 49N is right but there is no solution here<br>Mass of body = 50kgvolume = 0.049 m^3Since the density of body is more than density of water, it will sink.When it sinks, it will displace equal volume of water.So volume of water displaced = 0.049 m^3mass of water = density × volume = 1000×0.049 = 49kgbuoyancy = weight of water displaced=> buoyancy= mg=> buoyancy= 49×10 = 490NHence, buoyant force is 490N<br>The buoyant force is 490 N.
