Question 1
1 / -0

Which of the following is based on Archimedes' principle?

A
Lactometer

B
Barometer

C
Anemometer

D
Speedometer

Solution

Lactometer is based on Archimedes' principle.
Question 2
1 / -0

The reading of a spring balance when a block is suspended from it in air is 60 N. This reading is changed to 40 N when the block is submerged in water. The specific gravity of the block must be

A
3

B
2

C
6

D
3/2

Solution

Specific gravity = Weight in air/Loss of weight in water = 60/(60 - 40) = 3
Question 3
1 / -0

The upthrust on a body immersed in a fluid is equal to the

A
mass of liquid displaced

B
weight of fluid displaced

C
volume of fluid displaced

D
density of fluid displaced

Solution

The upthrust on a body immersed in a fluid is equal to the weight of fluid displaced
Question 4
1 / -0

The buoyant force acting on a fully submerged body depends on

A
the mass of the body

B
the volume of the body

C
the depth of the point below the surface of water

D
None of the above

Solution

The buoyant force acting on a fully submerged body depends on the volume of the body.
Question 5
1 / -0

When a ship floats on water,

A
it does not displace water

B
the mass of water displaced is equal to the mass of the ship

C
the mass of water displaced is less than the mass of the ship

D
the mass of water displaced is greater than the mass of the ship

Solution

When a ship floats on water, the mass of water displaced is equal to the mass of the ship.
Question 6
1 / -0

When a piece of ice floating in a beaker of water completely melts, the level of water in the beaker

A
rises

B
falls

C
remains unchanged

D
rises or falls depending upon the quantity of ice and water
