= 4mg

Let the side length of square be 'a' then
potential at centre O is

(given)

= – Q – q + 2q + 2Q = 0 = Q + q = 0
= Q = – q

Ammeter is a device used to measure current. Since it has to allow the complete current flowing in the circuit through it, it has to be connected in series. For this reason, ammeters have very low values of resistances so that they do not add to the value of resistance connected in the circuit.

Explanation:A will become positive with respect to B because current  indused is in clockwise direction

A photon of wavelength 6000 nm collides with an electron at rest. After scattering, the wavelength of the scattered photon is found to change by exactly one Compton wavelength.

In the Geiger-Marsden experiment very small deflection of the beam was expected because positive charge and the negative electrons are distributed through the whole atom reducing electric field inside the atom.

Nuclear forces are short range attractive forces which balance the repulsive forces between the protons inside the nucleus.

The correct answer is c) 9

Given A=[2,4,5],B=[7,8,9]

To find: n(A×B)=?

A×B={(2,7),(2,8),(2,9),(4,7),(4,8),(4,9),(5,7),(5,8),(5,9)}

∴n(A×B)=9

The sign of the sinA and tanA in third quadrant is negative and positive.

Δ = 1/2 [2(1-8) -7(1-10) +1(8-10)]
= 47/2

In the question, it should be f’(2) instead of f”(2) 
Explanation:- f(x) = ∫(0 to x) log(1+x²)
f’(x) = 2xdx/(1+x²)
f’(2) = 2(2)/(1+(2)²)
= 4/5

The equation y = 2x − x² i.e. y – 1 = - (x - 1)² represents a downward parabola with vertex at (1, 1) which meets x – axis where y = 0 .i .e . where x = 0 , 2. Also , the line y = - x meets this parabola where – x = 2x − x² i.e. where x = 0 , 3. 
Therefore , required area is :

Zero vector is the unit vector having zero length, hence the direction is undefined.

The word ‘interval’ is critical in this sentence. You might want to ask yourself why use the word ‘between’ at all? You need the word because of the word ‘interval’. ‘Interval’ implies that something is happening. That something has two parts to it. ‘Interval between’ is the correct idiomatic expression. A is incorrect because it uses the verb form ‘recessing’, which is not connected to a recession in the economy. This type of recession is what the sentence is discussing. Choice C is the best answer.

Sentence A refers to a “victory"?. What victory? Sentences B and D seem to provide an answer. Sentence B talks of the Greek warriors in the Battle of Marathon while sentence D is a more general statement about Athenian warriors routing Persian invaders. So, both sentences A and B are likely to follow D. Which of these sentences comes immediately after D? Sentence A states that not long after the victory, the Greeks already began to look back at it and think that they could never match this past glory. This does make sense when placed immediately after D. Now, consider sentence B. It talks of the Marathonomachai warriors who fought the war being regarded as Athens’ Greatest Generation. This too, looks like a good option to follow D. So, we need to look at some other clues to help us finalize the sentence order.

Sentences B and C make references to time. B talks of the 490 BCE war and C, of the mid- fifth century BCE (around 450 BCE). Note that in terms of timeline, B precedes C.

Now, C talks of Athenians “looking back with longing"?. To what? D provides an answer: a few decades earlier, Athenian citizen-soldiers had helped to rout the Persian invaders of Greece. So, D follows C.

If A were to follow D, we cannot place B in the paragraph. However, the sentence order BA does make sense after CD. So, the correct order is CDBA.

The question is " Arrange the sentences in the correct order "
The order is CDBA

Hence, the answer is CDBA
Choice D is the correct answer.
