Air Force Vayu 02/2027 English Exam Analysis

The English section included questions from vocabulary, spelling, idioms, subject-verb agreement, and active-passive voice. Candidates were tested on commonly used English rules and word meanings.

Vocabulary and Word Usage

Important vocabulary-based questions included:

• Scare: Means to cause fear or panic. Its synonym is frighten, while reassure can be used as an antonym in the given context.

• Remarkable: Means striking, unusual, or noteworthy. A suitable synonym is exceptional.

• Scarcity: Refers to a shortage or lack of something. Its synonyms include paucity and lack, while antonyms include abundance, excess, plethora, and profuse.

• Eminent: Refers to a person who is distinguished, famous, or prominent in a particular field.

• Abstract Noun: The abstract noun formed from bright is brightness.

• Correct Spelling: Occurrence is spelled with double 'c' and double 'r'.

• Idiom: A stitch in time saves nine means that solving a problem at an early stage can prevent a bigger problem later.

Subject-Verb Agreement

Questions were also based on subject-verb agreement with distributive expressions such as each of, either of, neither of, and one of.

The basic rule is:

Distributive expression + plural noun/pronoun + singular verb

For example:

• Incorrect: Each of the substances are found in India.

• Correct: Each of the substances is found in India.

Active and Passive Voice

The section also tested passive voice formation with infinitives.

The general transformation is:

Active: to + V1

Air Force Vayu 02/2027 General Awareness Exam Analysis

The General Awareness section included questions from Indian History, Constitution, Geography, Defence, Sports, and General Science.

Modern Indian History

One question was related to the All-India Muslim League, which was founded in 1906 at Dhaka.

Candidates should also revise important socio-religious reform movements such as:

• Brahmo Samaj

• Arya Samaj

• Ramakrishna Mission

Indian Polity and Constitution

Questions from Indian Polity included constitutional provisions related to the President and Prime Minister.

• Article 78: Deals with the duties of the Prime Minister with respect to furnishing information to the President.

• Article 74: Provides for a Council of Ministers headed by the Prime Minister to aid and advise the President.

Geography and Important Landmarks

Important topics included deserts and Indian heritage sites.

• Antarctica: Known as the world's coldest desert.

• Ladakh: Commonly identified as India's cold desert.

• Sahara: World's largest hot desert.

• Konark Sun Temple: A famous 13th-century temple located in Odisha.

Defence, Sports and Current Affairs

The section also included questions related to defence and sports.

Project Kusha was among the defence-related topics. It is associated with India's planned long-range surface-to-air missile system.

A sports-related question referred to Jasmine's gold medal in boxing at the Commonwealth Games.

Air Force Vayu 02/2027 General Science Analysis

The Biology portion included questions related to the endocrine system and hormones.

Pituitary Gland and Growth Hormone

The pituitary gland is commonly called the Master Gland because it regulates the activities of several other endocrine glands through its hormones.

Growth Hormone (GH), also known as somatotropin, is produced by the anterior pituitary gland and plays an important role in growth and development.

Air Force Vayu 02/2027 Mathematics Exam Analysis

The Mathematics section included questions from calculus, matrices, permutations, probability, trigonometry, coordinate geometry, arithmetic, and related topics.

Calculus and Integration

A standard logarithmic integral was tested:

∫ (1/x) dx = ln|x| + C

Integration by parts can be applied to expressions such as:

∫ x ln x dx = (x²/2) ln x − x²/4 + C

The ILATE rule can be used to select the first function while applying integration by parts.

Matrices and Determinants

For an n × n matrix A:

|adj(A)| = |A|ⁿ⁻¹

For a 3 × 3 matrix with:

|A| = 2

we get:

|adj(A)| = 2² = 4

The double-adjoint property can be represented as:

|adj(adj(A))| = |A|^(n−1)²

Inverse of a 2 × 2 Matrix

For:

A = [[a, b], [c, d]]

the determinant is:

|A| = ad − bc

provided the determinant is non-zero,

A⁻¹ = 1/(ad − bc) [[d, −b], [−c, a]]

Permutations

For the six-letter word PLAYER, all letters are different.

Number of arrangements = 6! = 720

For ASSUME, the letter S occurs twice:

Number of arrangements = 6!/2! = 360

Conditional Probability

The conditional probability formula is:

P(A|B) = P(A ∩ B)/P(B)

Therefore:

P(A ∩ B) = P(A|B) × P(B)

Trigonometry

The odd-function property of sine is:

sin(−x) = −sin x

A trigonometric equation such as:

2cos²x − 3sin x = 0

can be converted using cos²x = 1 − sin²x and solved as a quadratic equation in sin x.

Complex Numbers

For:

z = 1 + i

the principal argument is:

Arg(z) = π/4

Arithmetic Progression

If the sum of n terms is:

Sₙ = 3n² + 2n

then:

• First term = 5

• Second term = 11

• Common difference = 6

Average Speed

When equal distances are covered at speeds x and y, the average speed is:

Average speed = 2xy/(x + y)

Area of a Border Path

For a rectangular field measuring 18 m × 12 m with a uniform path of width 2 m around it:

Outer dimensions:

22 m × 16 m

Therefore:

Area of path = (22 × 16) − (18 × 12)

= 352 − 216 = 136 m²

Air Force Vayu 02/2027 Physics Exam Analysis

The Physics section covered mechanics, thermodynamics, dimensional analysis, electricity, magnetism, waves, optics, and properties of magnetic materials.

Projectile Motion

For a body projected vertically upward with initial velocity u, the time taken to reach maximum height is:

t = u/g

For u = 20 m/s and g = 10 m/s²:

t = 20/10 = 2 seconds

The total time of flight is:

T = 2u/g = 4 seconds

Thermodynamics

The Carnot engine efficiency formula is:

η = 1 − T₂/T₁

where:

• T₁ = temperature of the source

• T₂ = temperature of the sink

For an isothermal process, temperature remains constant. For an ideal gas, the change in internal energy is therefore zero.

For an adiabatic process, there is no heat exchange:

Q = 0

The relation for a reversible adiabatic process is:

PVᵞ = constant

Dimensional Analysis

For an equation:

Force = K × velocity × time

the dimensions of K are:

[K] = [Force]/([velocity] × [time])

Therefore:

[K] = M T⁻²

Electromotive Force

Electromotive force is defined as work done per unit charge:

EMF = Work/Charge

Its SI unit is Volt (V).

1 Volt = 1 Joule/Coulomb

Quantisation of Charge

Electric charge is quantised according to:

q = ne

where n is an integer and e is the elementary charge.

Resistance of a Wire

Resistance is given by:

R = ρl/A

For a circular wire:

A = πr²

Therefore:

R = ρl/(πr²)

If the radius of the wire is doubled, its cross-sectional area becomes four times larger. Hence, the resistance becomes:

R/4

Torque on an Electric Dipole

The magnitude of torque acting on an electric dipole placed in an electric field is:

τ = pE sinθ

where p is the electric dipole moment, E is the electric field, and θ is the angle between them.

Waves and Optics

The wave equation:

y = A sin(ωt − kx)

represents a wave travelling in the positive x-direction.

The lens formula is:

1/f = 1/v − 1/u

Magnetic Materials Classification

Questions related to magnetic materials were also included in the Physics section.

Permanent and Temporary Magnets

Soft iron is preferred for temporary magnets and electromagnets because it has high permeability and low retentivity.

Steel is commonly used for permanent magnets because of its comparatively high retentivity and coercivity.
