When a boat is partially immersed in water, it displaces 600 kg of water. How much is the buoyant force acting on the boat in newtons ? (g = 10 m s-2)
If a fresh egg is put into a beaker filled with water, it sinks. On dissolving a lot of salt in the water, the egg begins to rise and then floats. Why ?
Distinguish between density and relative density.
How does the pressure exerted by thrust depend on the area of surface on which it acts? Explain with a suitable example.
The pressure P1 at the top of a dam and P2 at a depth h form the top inside water (density p) are related as :
Will a body weigh more in air or vacuum when weighed with a spring balance? Give a reason for your answer.

(i) The volume of the body,
(ii) The loss in weight of the body, and
(iii) The upthrust on the body.
State the assumption made in part (i).
Assertion (A): The buoyant force on a submerged rigid object can be considered to be acting at the center of mass of the object.
Reason (R): In rigid body, force distributed uniformly through its volume can be considered to be acting at the centre of mass of the body.
