NEET 2021 Physics Questions
Use this page to connect the official 2021 paper with current Physics practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 3/5
A series LCR circuit has R = 9 Ω, inductive reactance XL = 15 Ω and capacitive reactance XC = 3 Ω at the frequency of the applied source. The impedance of the circuit is:
- A. 27 Ω
- B. 15 Ω
- C. 21 Ω
- D. 18 Ω
Example 3 · difficulty 4/5
A series LCR circuit contains an inductor of 8 H and a capacitor of 0.5 μF. The angular frequency of the source at which the circuit resonates is:
- A. 1000 rad s⁻¹
- B. 250 rad s⁻¹
- C. 500 rad s⁻¹
- D. 125 rad s⁻¹
The evidence-first practice loop
- 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
- 2. Attempt closed-bookExpose the concept or execution gap before rereading.
- 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions
Are these official NEET 2021 Physics PYQs?
No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.
How should I use the NEET 2021 paper?
Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
