2 2 and 3 only
3 1 and 3 only

When a ship floats on water :
1 it displaces no water
2 the mass of water displaced is equal to the mass of the ship
3 the mass of water displaced is lesser than the mass of the ship
4 the mass of water displaced is greater than the mass of the ship
Explanation:
B According to the principle of flotation, the weight of a floating body is equal to the weight of the liquid displaced by its submerged part. Therefore, ship is able to float in water because its weight is same as the weight of the water it displaces.

For a steel boat floating on a lake, the weight of the water displaced by the boat is
1 less than the weight of the boat
2 more than the weight of the boat
3 equal to the weight of the part of the boat which is below the water level of the lake
4 equal to the weight of the boat
Explanation:
D According to Archimedes principle, when an object submerged in a fluid is acted upon by an upward force whose magnitude is equal to the weight of the fluid displaced. This upward force is called as Buoyant force. Hence boat is floating in water, so its weight will be balanced by buoyancy force $\left(\mathrm{F}_{\mathrm{b}}\right)$. Buoyancy force $\left(\mathrm{F}_{\mathrm{b}}\right)=$ Weight $(\mathrm{W})$ of the boat.

Whether an object will float or sink in a liquid, depends on
1 mass of the object only
2 mass of the object and density of liquid only
3 difference in the densities of the object and liquid
4 mass and shape of the object only
Explanation:
C Floatation and sinking of an object is dependent upon the relative density with each other. If the density of the object is more than the density of the liquid, the object will sink and if the density of an object is less than the liquid then it will float over it. Therefore, the sinking or floating of an object depends on the difference of density of the object and liquid.
