Physics — NEET 2023 sample questions
NEET 2023 · Question 1
A projectile is launched at 280 m/s at 30° above horizontal. Find its maximum height (take g = 9.8 m/s²).
- A.3000 m
- B.2800 m
- C.2000 m
- D.1000 m
Show answer and explanation
Answer: D. 1000 m
The vertical launch speed is 280 sin30° = 140 m/s.
The vertical launch speed is 280 sin30° = 140 m/s. At the highest point v_y=0, so H=u_y²/(2g)=140²/(19.6)=1000 m. This selects option 4.
NEET 2023 · Question 2
An electric dipole of length 2 cm in a uniform field 2×10⁵ N/C experiences a torque of 4 N·m when it makes 30° with the field. Find the magnitude of either charge.
- A.2 mC
- B.8 mC
- C.6 mC
- D.4 mC
Show answer and explanation
Answer: A. 2 mC
Dipole torque is τ=pE sinθ=qℓE sinθ.
Dipole torque is τ=pE sinθ=qℓE sinθ. Substituting τ=4, ℓ=0.02 m, E=2×10⁵ and sin30°=1/2 gives q=2×10⁻³ C. Therefore the charge is 2 mC.
NEET 2023 · Question 3
A soap bubble has radius 2 cm and surface tension 0.03 N/m. What surface energy is required to create it?
- A.50.1×10⁻⁴ J
- B.30.16×10⁻⁴ J
- C.5.06×10⁻⁴ J
- D.3.01×10⁻⁴ J
Show answer and explanation
Answer: D. 3.01×10⁻⁴ J
A soap bubble has two surfaces, so surface energy is 2T·4πr²=8πTr².
A soap bubble has two surfaces, so surface energy is 2T·4πr²=8πTr². With r=0.02 m and T=0.03 N/m, U≈3.01×10⁻⁴ J. Hence option 4.
Chemistry — NEET 2023 sample questions
NEET 2023 · Question 51
Match carbon allotrope/material with property: coke, diamond, fullerene and graphite; properties include reducing agent, sp³ lattice, cage structure and dry lubricant.
- A.A-I, B-II, C-IV, D-III
- B.A-II, B-I, C-III, D-IV
- C.A-IV, B-III, C-II, D-I
- D.A-I, B-II, C-III, D-IV
Show answer and explanation
Answer: D. A-I, B-II, C-III, D-IV
Coke is used as a reducing agent, diamond is an sp³ network, fullerenes have cage-like structures and graphite acts as a dry lubricant due to its layered structure.
Coke is used as a reducing agent, diamond is an sp³ network, fullerenes have cage-like structures and graphite acts as a dry lubricant due to its layered structure. The matching is represented by option 4. Hence the stored answer index points to option 4.
NEET 2023 · Question 52
Assertion: Sodium dissolves in liquid ammonia to give a deep-blue paramagnetic solution. Reason: The colour and paramagnetism are due to formation of sodium amide.
- A.Both true, R explains A
- B.Both true, R not explanation
- C.A false, R true
- D.A true, R false
Show answer and explanation
Answer: D. A true, R false
Sodium in liquid ammonia forms solvated electrons, which produce the deep-blue colour and paramagnetism.
Sodium in liquid ammonia forms solvated electrons, which produce the deep-blue colour and paramagnetism. Sodium amide is not the species responsible for these properties. Thus the assertion is true but the reason is false.
NEET 2023 · Question 53
In the chain Ph–CH=CH–CH(X)–CH₂CH₃, classify the carbon bearing X relative to the double bond.
- A.Vinylic
- B.Benzylic
- C.Aryl
- D.Allylic
Show answer and explanation
Answer: D. Allylic
An allylic carbon is an sp³ carbon directly adjacent to a C=C double bond.
An allylic carbon is an sp³ carbon directly adjacent to a C=C double bond. The carbon bearing X is next to the alkene, so it is allylic. Option 4.
Botany — NEET 2023 sample questions
NEET 2023 · Question 101
Which process moves ions across a membrane against their electrochemical gradient using metabolic energy?
- A.Active transport
- B.Facilitated diffusion
- C.Osmosis
- D.Simple diffusion
Show answer and explanation
Answer: A. Active transport
Movement against a concentration/electrochemical gradient requires energy and carrier proteins or pumps.
Movement against a concentration/electrochemical gradient requires energy and carrier proteins or pumps. This is active transport, usually driven directly or indirectly by ATP. Option 1.
NEET 2023 · Question 102
Which factor is considered the most important cause in the 'evil quartet' of biodiversity loss?
- A.Co-extinction
- B.Habitat loss and fragmentation
- C.Over-exploitation
- D.Alien-species invasion
Show answer and explanation
Answer: B. Habitat loss and fragmentation
Habitat destruction and fragmentation eliminate living space and isolate populations, affecting very large numbers of species simultaneously.
Habitat destruction and fragmentation eliminate living space and isolate populations, affecting very large numbers of species simultaneously. NCERT identifies habitat loss and fragmentation as the most important cause. Option 2.
NEET 2023 · Question 103
In genome analysis, what does EST stand for/represent?
- A.All repeated sequences
- B.Expressed sequence tags from genes expressed as RNA
- C.Only regulatory DNA
- D.Only introns
Show answer and explanation
Answer: B. Expressed sequence tags from genes expressed as RNA
ESTs are short sequences derived from expressed RNA/cDNA and therefore tag genes that are being transcribed.
ESTs are short sequences derived from expressed RNA/cDNA and therefore tag genes that are being transcribed. They are used to identify expressed genes. Option 2.
Zoology — NEET 2023 sample questions
NEET 2023 · Question 151
Assertion: Mammalian nephrons are cortical or juxtamedullary. Reason: Cortical nephrons have longer loops of Henle than juxtamedullary nephrons.
- A.Both true
- B.Both false
- C.A false, R true
- D.A true, R false
Show answer and explanation
Answer: D. A true, R false
The two nephron types are correctly recognized, so the assertion is true.
The two nephron types are correctly recognized, so the assertion is true. Juxtamedullary nephrons, not cortical ones, have long loops that extend deep into the medulla. Thus the reason is false.
NEET 2023 · Question 152
Match eye structures fovea, iris, blind spot and sclera with their descriptions.
- A.A-I, B-II, C-III, D-IV
- B.A-III, B-I, C-IV, D-II
- C.A-IV, B-II, C-I, D-III
- D.A-II, B-III, C-IV, D-I
Show answer and explanation
Answer: B. A-III, B-I, C-IV, D-II
The fovea is the region of highest visual acuity, the iris regulates pupil size, the blind spot lacks photoreceptors at the optic-nerve exit, and sclera is the tough outer coat.
The fovea is the region of highest visual acuity, the iris regulates pupil size, the blind spot lacks photoreceptors at the optic-nerve exit, and sclera is the tough outer coat. This produces the mapping in option 2. Accordingly, the selected G1 choice is option 2.
NEET 2023 · Question 153
Which cellular component provides structural support and is important in cell motility, intracellular transport and shape?
