Test: Archimedes Principle (Old Syllabus) - Question 1

### An object weighing 5 N in air, weighs 4.5 N a liquid. The buoyant force experienced by the object is

Detailed Solution for Test: Archimedes Principle (Old Syllabus) - Question 1

The buoyant force experienced by the object is:- The buoyant force is in opposite direction to the weight of the object. Hence, if the object weighs 4.5 N in liquid then 0.5 N buoyant force will act on the object.

Test: Archimedes Principle (Old Syllabus) - Question 2

### The same body is immersed in two liquids A and B in succession. The extent to which the body sinks in liquid B is less then in liquid A. What are the conclusions that could be derived from such an observation

Detailed Solution for Test: Archimedes Principle (Old Syllabus) - Question 2

The density of liquid B is more than the liquid A as more upthrust is exerted on the body in liquid B and hence it sinks less.

Test: Archimedes Principle (Old Syllabus) - Question 3

### A sample of milk diluted with water has density 1036kgm−3. if pure milk has a density 1080kgm−3 what is the percentage of water by volume in milk ?

Detailed Solution for Test: Archimedes Principle (Old Syllabus) - Question 3

Test: Archimedes Principle (Old Syllabus) - Question 4

A student lowers a body in a liquid filled in a container. He finds that there is a maximum apparent loss in weight of the body when

Test: Archimedes Principle (Old Syllabus) - Question 5

The density of copper is 9 g/cm3. Then the volume of 90 g copper is​

Detailed Solution for Test: Archimedes Principle (Old Syllabus) - Question 5

Density of copper = 9 gm/cm^3
Mass of copper  =  90 g
We know;  Density =  mass / volume
⇒ volume  = mass / density
⇒    90 / 9
⇒ Volume  = 10 cm3

Test: Archimedes Principle (Old Syllabus) - Question 6

The sea water is denser than fresh water due to

Detailed Solution for Test: Archimedes Principle (Old Syllabus) - Question 6

Density is defined as the mass per unit volume. In seawater, the salts are dissolved in water resulting in an increase in their mass per unit volume. Hence, seawater is denser than freshwater because of the dissolved salts in seawater, its density increases.

Test: Archimedes Principle (Old Syllabus) - Question 7

Instrument used for measuring the density or relative density of liquids is known as

Test: Archimedes Principle (Old Syllabus) - Question 8

A packet of 400 g and volume 200 cm3 is put in a water tank. The relative density of packet is

Test: Archimedes Principle (Old Syllabus) - Question 9

An object of weight 500 N is floating in a liquid. The magnitude of buoyant force acting on it is

Detailed Solution for Test: Archimedes Principle (Old Syllabus) - Question 9
As we know that the buoyant force acting on a floating body in a liquid is equal to the weight of the floating body,
Buoyant force acting on the body of weight 200N floating in  liquid = 200N
Test: Archimedes Principle (Old Syllabus) - Question 10

If relative density is 11.3, the density of the substance in SI units is

Test: Archimedes Principle (Old Syllabus) - Question 11

If the density of the object placed in a liquid is equal to the density of the liquid, the object will:

Detailed Solution for Test: Archimedes Principle (Old Syllabus) - Question 11

If the density of the object placed in liquid is equal to the density of the liquid, then :- It would float submerged in the liquid. Some part of the solid would be above the liquid surface and part would be inside the liquid surface.

Test: Archimedes Principle (Old Syllabus) - Question 12

The mass of water displaced by a solid of mass 400 g and volume 150 cm3 is​

Detailed Solution for Test: Archimedes Principle (Old Syllabus) - Question 12
Test: Archimedes Principle (Old Syllabus) - Question 13

Three objects A, B, and C having density 1.12 g cm-3, 0.92 g cm-3 and 2.02 g cm-3 respectively, are placed in a water tank. Which object will sink in water tank?​

Test: Archimedes Principle (Old Syllabus) - Question 14

When a solid body is fully immersed in a liquid, the volume of the displaced liquid is:

Detailed Solution for Test: Archimedes Principle (Old Syllabus) - Question 14
According to Archimedes’ principle, the volume of liquid displaced is equal to the volume of the solid.
Test: Archimedes Principle (Old Syllabus) - Question 15

If we want to determine the volume of a solid by immersing it in water, the solid should be

Detailed Solution for Test: Archimedes Principle (Old Syllabus) - Question 15
It should be heavier than water and insoluble in it, so that it sinks and displaces the water and also it does not mix in the water.
