- A. 12 J
- B. 16 J
- C. 24 J
- D. 8 J

NEET 2023 Physics Work, Energy and Power Questions
Use this page to connect the official 2023 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.
What to master
work-energy theorem, conservative forces, power and collisions.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 2/5
A spring of force constant 100 N/m is slowly stretched from its natural length to an extension of 0.20 m. What is the work done by the external agent on the spring?
- A. 1 J
- B. 4 J
- C. 2 J
- D. 20 J
Example 3 · difficulty 3/5
A spring with force constant 200 N/m is stretched from an extension of 0.10 m to 0.30 m. What is the work done by the spring force during this process?
- A. 8 J
- B. −6 J
- C. 6 J
- D. −8 J
The evidence-first practice loop

Frequently asked questions
Are these official NEET 2023 Physics Work, Energy and Power 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 2023 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.
