NEET 2020 Physics Questions
Use this page to connect the official 2020 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 1/5
The voltage of an AC source varies with time as v = 311 sin(100πt) volt, where t is in second. The rms value of this voltage is closest to:
- A. 110 V
- B. 155.5 V
- C. 220 V
- D. 311 V
Example 3 · difficulty 2/5
A pure inductor of self-inductance 0.1 H is connected across a 110 V (rms), 50 Hz AC supply. Neglecting the coil resistance, the rms current through the inductor is approximately:
- A. 3.5 A
- B. 7.0 A
- C. 1.75 A
- D. 35 A
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 2020 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 2020 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.
