Important Questions of Thrust, Pressure and Floatation
Q1.What is meant by buoyancy? Why does an object float or sink when placed on the surface of liquid?
Q2.A metallic cube of mass 9 kg and dimension 5 cm X 8cm X 25 cm is placed on a table to exert pressure on its surface if g= 10 m/s2, the maximum pressure which can be achieved by the cubiod will be
Q3.What are the factors on which buoyant force depends?
Q4.State any two daily life phenomenon which are based on Archimedes's principle.Discuss the role of Archimedes principle in Defense industry
Q5.State Archimedes' principle.How will you verify it Experimentally.What are its applications
Q6.State difference between Density and Relative density
Q7.If relative density of body is 6.2, what will be its density in SI unit
Q8.Define thrust and pressure
Q9.State the principle of Floatation for an object of weight W immersed in a fluid.
