NEET Physics Questions Types

1. Formula‑Based NEET Numericals

Most rewarding category in NEET Physics. It has direct substitution of formulas such as electric field calculation, lens power, terminal voltage, and Kepler’s third law.

Question:
A particle of mass $m$ is projected from the surface of Earth with velocity $v = kV_e$ $(k < 1)$, where $V_e$ is the escape velocity. The maximum height reached above the surface of Earth is:

Options:
(1) $\dfrac{Rk}{(1 - k)^2}$
(2) $\dfrac{Rk}{(1 + k)^2}$
(3) $\dfrac{Rk^2}{(1 + k)}$
(4) $\dfrac{Rk^2}{(1 - k^2)}$

Correct Answer: (4) $\dfrac{Rk^2}{(1 - k^2)}$

Explanation:
Using energy conservation:
Initial energy $= \dfrac{1}{2}mv^2 - \dfrac{GMm}{R}$
Final energy at max height $= -\dfrac{GMm}{R + h}$

So,
$\dfrac{1}{2}mv^2 = GMm\left(\dfrac{1}{R} - \dfrac{1}{R + h}\right)$

Substitute $v = k\sqrt{2gR}$:
$\dfrac{1}{2}m(2gRk^2) = GMm\left(\dfrac{1}{R} - \dfrac{1}{R + h}\right)$

Solving gives:
$h = \dfrac{Rk^2}{1 - k^2}$

2. Direct Conceptual NEET MCQs

It is the most reliable scoring zone from Units & Measurements, Electromagnetic Waves, and Semiconductor Electronics. It examines direct single NCERT facts or definitions.

Question:
Plane angle and solid angle have:

Options:
(1) Both units and dimensions
(2) Units but no dimensions
(3) Dimensions but no units
(4) No units and no dimensions

Correct Answer: (2) Units but no dimensions

Explanation:
Plane angle (radian) $= \dfrac{\text{arc}}{\text{radius}}$ → dimensionless
Solid angle (steradian) $= \dfrac{\text{area}}{r^2}$ → dimensionless

Thus, both are dimensionless quantities but have defined SI units (radian and steradian).

3. Graph-Identification NEET Questions

It is a commonly asked question in Kinematics, Oscillations, and Capacitor Discharge. These are highly predictable (example: v‑t graph of a ball in viscous liquid reaching terminal velocity)

Question:
A spherical ball is dropped in a long column of highly viscous liquid. Which curve represents speed $(v)$ as a function of time $(t)$?

Options:
(1) a
(2) b
(3) c
(4) d

Correct Answer: (2) b

Explanation:
Initially, the ball accelerates due to gravity. As velocity increases, viscous drag and buoyant force increase. Eventually, drag + buoyancy = weight ⇒ net force becomes zero, and the ball attains terminal velocity.

Thus, speed increases initially and then becomes constant (the graph shows a rising curve that flattens).

4. Statement‑Based / Assertion‑Reason NEET Questions

These tests the conceptual clarity and logical reasoning rather than formula recall. Toppers treat them as high‑accuracy because the options are predictable once the concept is clear.

Question:
Statement I: Biot-Savart law gives magnetic field for an infinitesimal current element only.
Statement II: It is analogous to Coulomb's law with $I d\ell$ being the scalar source.

Options:
(1) Both correct; II explains I
(2) Both correct; II does not explain I
(3) I correct; II incorrect
(4) I incorrect; II correct

Correct Answer: (3) I correct; II incorrect

Explanation:
Statement I is correct — Biot-Savart law gives $dB$ due to an infinitesimal current element $I d\ell$. To find the total magnetic field, we integrate over the conductor.

Statement II is incorrect — $I d\ell$ is a vector quantity, whereas charge $q$ in Coulomb’s law is a scalar. Although there is an analogy between the laws, the nature of the source quantities is different.

5. NEET Diagram‑Based Physics Questions

These questions test whether aspirants can interpret circuit diagrams, waveforms, or graphical setups correctly under exam pressure.

Question:

A full wave rectifier circuit uses diodes $D_1$ and $D_2$. The input is $V_{in} = 220\sin(100\pi t)\ \text{V}$. At $t = 15\ \text{ms}$ the state of diodes is:

(1) $D_1$ forward biased $D_2$ reverse biased
(2) $D_1$ reverse biased $D_2$ forward biased
(3) Both forward biased
(4) Both reverse biased

Correct Answer: $D_1$ reverse biased $D_2$ forward biased

Explanation:
Put $t = 0.015\ \text{s}$ in the given expression.
$V = 220\sin(100\pi \times 0.015) = 220\sin(1.5\pi) = -220\ \text{V}$.
This is the negative half cycle of AC input.
So $D_2$ conducts while $D_1$ remains reverse biased.

NEET Chemistry Questions Types

1. Numerical Chemistry Questions

These are found mainly in physical chemistry chapters (Bohr model, Chemical Kinetics, Thermodynamics). It has a direct formula application with unit conversion.

Question:
The half-life of a first-order reaction is 1 minute. The time required for 99.9% completion is closest to:

Options:
(1) 2 minutes
(2) 4 minutes
(3) 5 minutes
(4) 10 minutes

Correct Answer: (4) 10 minutes

Explanation:
For a first-order reaction:
Number of half-lives required for 99.9% completion $\approx 10$
(since $\log 1000 = 3\log 10$)

Thus,
$t = 10 \times t_{1/2} = 10 \times 1 = 10,\text{minutes}$

2. Direct NCERT-Based NEET Questions

These are straight factual MCQs from the NCERT lines. It is common in Inorganic Chemistry and p‑Block elements.

Question:
Dalton's Atomic Theory could NOT explain which of the following?

Options:
(1) Law of conservation of mass
(2) Law of constant proportion
(3) Law of multiple proportions
(4) Law of gaseous volumes

Correct Answer: (4) Law of gaseous volumes

Explanation:
Dalton’s atomic theory successfully explains the laws of conservation of mass, constant proportion, and multiple proportion.

However, it could not explain Gay-Lussac's law of gaseous volumes, because Dalton did not consider the molecular (e.g., diatomic) nature of gases.

3. Statement‑Based Questions

Two statements are given, and these test correctness and explanation. It is common in Acid strength trends, drug classification, and bonding concepts.

Question :

Statement I: Aspirin and Paracetamol belong to the class of narcotic analgesics.
Statement II: Morphine and Heroin are non-narcotic analgesics.

Options:
(1) Both true
(2) Both false
(3) I correct; II incorrect
(4) I incorrect; II correct

Correct Answer: (2) Both false

Explanation:
Both statements are incorrect. Aspirin and Paracetamol are non-narcotic analgesics, while Morphine and Heroin are narcotic analgesics.

Question :

Statement I: Acid strength increases: $HF \ll HCl \ll HBr \ll HI$
Statement II: As size increases down the group, bond strength of $H\text{-}X$ decreases and acid strength increases.

Options:
(1) Both true
(2) Both false
(3) I correct; II incorrect
(4) I incorrect; II correct

Correct Answer: (1) Both true

Explanation:
Both statements are correct. As we move down the group, atomic size increases, bond strength of $H\text{-}X$ decreases, making ionization easier. Hence, acid strength increases in the order:
$HF < HCl < HBr < HI$.

4. Diagram‑Based Questions

These identify reactions or products using structural diagrams. Common in Organic Chemistry (Hinsberg test, functional groups).

Question:

Identify the compound that reacts with Hinsberg reagent to give a solid that dissolves in alkali.

Correct Answer: (C) CH₃–NH₂ type (primary amine)

Explanation:
Primary amines react with Hinsberg’s reagent to form a sulphonamide containing an N–H bond, which is acidic and dissolves in alkali.

Secondary amines form sulphonamides without N–H, so they are insoluble in alkali.
Tertiary amines do not react with Hinsberg’s reagent.

5. Match List Questions

Match compounds with properties (magnetic moment, oxidation state, ligand field). Common in Coordination Compounds.

Question:
