QUESTION: 3

A vessel of height 2d is half filled with a liquid of refractive index √2 and the other half with a liquid of refractive index n (the given liquids are immiscible). Then, the apparent depth of the inner surface of the bottom of the vessel (neglecting the thickness of the bottom of the vessel) will be

Solution:

The depth of the image of an object submerged in a transperent medium; it is reduced from the real depth of the object by a factor equal to the relative index of refraction of the medium with respect to air.

Refractive index μ = 

For 1st liquid  

Similarly, for 2nd liquid, 

Total apparent depth = x1  + x2

 

QUESTION: 4

A shell of mass 20 kg at rest explodes into two fragments whose masses are in the ratio 2 : 3. The smaller fragment moves with a velocity of 6 m/s. The kinetic energy of the larger fragment is

Solution:

 

Total mass of the shell = 20 kg

Ratio of the masses of the fragments = 2: 3 

∴ Masses of the fragments are 8 kg and 12 kg Now, according to the conservation of momentum , m1v= m2v2

∴ 8 × 6 = 12 × v

 v (velocity of the larger fragment) = 4 m/s

Kinetic energy

Similarly the capacitor with k as dielectric constant has capacitance

QUESTION: 8

Three concurrent coplanar forces 1 N, 2 N and 3 N acting along different directions on a body

Solution:

We can clearly see that the first two forces 1N,2N if they are in the same direction, then they would equal to the third force 3N. But it is given that the three forces are in different directions. So there is no possibility of equilibrium with these forces in different directions.

QUESTION: 9

QUESTION: 10

Horizontal tube of non-uniform cross-section has radii of 0.1 m and 0.05 m respectively at M and N. For a streamline flow of liquid, the rate of liquid flow is

Solution:

According to principle of continuity, for streamline flow of fluid 
through a tube of non-uniform cross-section the rate of flow of fluid 
(Q) is same at every point in the tube. 
i.e, Av = constant
Therefore, the rate of flow of fluid is same at M and N.  

QUESTION: 11

QUESTION: 14

If two soap bubbles of different radii are connected by a tube, then

Solution:

The excess pressure inside the soap bubble is inversely proportional to the radius of soap bubble i.e. P ∝1/r, r being the radius of the bubble. It follows that pressure inside a smaller bubble is greater than that inside a bigger bubble. Thus, if these two bubbles are connected by a tube, air will flow from smaller bubble to bigger bubble and the bigger bubble grows at the expense of the smaller one.

QUESTION: 15

 The thermo emf of a hypothetical thermocouple varies with the temperature e of hot junction as E = aθ + bθ2 in volts, where the ratio a / b is 700°C. If the cold junction is kept at O°C, then the neutral, temperature is

Solution:

The thermo emf is given by E = aθ + bθ2

For neutral temperature 

⇒ a + 2bθ= 0

But neutral temperature can never be negative (less than zero) i.e.,  θn< |0oC|

 Hence, no neutral temperature is possible for this thermocouple.

QUESTION: 21

A magnetic field exerts no force on

Solution:

A moving electric charge has a magnetic field associated with it. So, it's magnetic field interacts with the external magnetic field and a force is exerted on the moving charge.
But, a fixed charge does not have any magnetic field associated with it, so id does not experience any force in a magnetic field.

QUESTION: 28

 Two rectangular blocks A and B of masses 2 kg and 3 kg respectively are connected by a spring of spring constant 10.8 Nm-1 and are placed on a frictionless horizontal surface. The block A was given an ‘initial velocity of 0.15 ms-1 in the direction shown in the figure. The maximum compression of the spring during the motion is​

Solution:

As the block A moves  with velocity 0.15ms−1, it compresses the  spring which pushes B towards right. A goes on compressing the spring till the velocity acquired by B becomes equal to the velocity of A, ie, 0.15ms−1,

Let this velocity be v. Now, spring is in a state of maximum compression. Let x be the maximum compression at this stage. 

According to the law of conservation of linear momentum, we get  mAu = (mA+mB)v or v = 

According to the law of conservation of energy, 

 

QUESTION: 29

0.1 mof water at 80°C is mixed with 0.3 mof water at 60°C. The final temperature of the mixture is

Solution:

Let T°C be final temperature of the mixture.

Heat lost = Heat gained
∴ 0.1× 103 × swater × (80−T)
= 0.3 × 103 × swater × (T−60)
⇒ T = 65C

QUESTION: 32

 A wheel of radius 0.4 m can rotate freely about its axis as shown in the figure. A string is wrapped over its rim and a mass of 4 kg is hung. An angular acceleration of 8 rad- s-2 is produced in it due to the torque. Then, moment of inertia of the wheel is (g = 10 ms-2)

QUESTION: 33

An object start sliding on a frictionless inclined plane and from same height another object start falling freely.

Solution:

Both start with the same potential energy component ( gh )

When they both reach the ground, both have converted that identical energy component kinetic energy.

Thus, the object sliding down a frictionless incline will reach the same velocity as the one dropped straight down.

The times to reach the speed to reach the speed will not be the same, the dropped one will reach it faster.

QUESTION: 34

A boy on a cycle pedals around a circle of 20 metres radius at a speed of 20 m/s, The combined mass of the body and the cycle makes with the vertical so that it may not fall is (g = 9.8 m/ s2) .

Solution:

A body that travels an equal distance in equal amounts of time along a circular path has a constant speed but not constant velocity. This is because velocity is a vector and thus it has magnitude as well as direction.

v = ( Rg tanθ )1/2

QUESTION: 35

A coin is dropped in a lift. It takes time tto reach the floor when lift is stationary. It takes time t2 when lift is moving up with constant acceleration. Then,

Gel electrophoresis is used for

Solution: Gel electrophoresis is a technique commonly used in laboratories to seperate charged molecules like DNA ,RNA and Protein according to their size. Charged molecules move through a gel when an electric current is passed across it. An electric current is applied across the gel so that one end of the gel has a positive charge and the other end has a negative charge. The movement of charged molecules is called migration. Moleces migrate towards the opposite charge. A molecule with a negative charge will therefore will be pull towards the positive end.
