Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 3/5

An alternating voltage is represented by v = 100 sin(ωt). If it first reaches its positive maximum after 0.005 s from a zero crossing with positive slope, the angular frequency is:

A. 50π rad s⁻¹
B. 100π rad s⁻¹
C. 200π rad s⁻¹
D. 100 rad s⁻¹

Example 2 · difficulty 3/5

An alternating voltage is represented by v = 100 sin(ωt). If it first reaches its positive maximum after 0.02 s from a zero crossing with positive slope, the angular frequency is:

A. 12.5π rad s⁻¹
B. 50π rad s⁻¹
C. 25π rad s⁻¹
D. 25 rad s⁻¹

Example 3 · difficulty 3/5

An alternating voltage is represented by v = 100 sin(ωt). If it first reaches its positive maximum after 0.0025 s from a zero crossing with positive slope, the angular frequency is:

A. 100π rad s⁻¹
B. 400π rad s⁻¹
C. 200 rad s⁻¹
D. 200π 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 2019 Physics Alternating Current 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 2019 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.
