NEET 2016 Physics Modern Physics Questions

Use this page to connect the official 2016 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 1 · difficulty 1/5

In a Geiger-Marsden type α-particle scattering experiment on a thin gold foil, it is observed that only about 1 in every 8000 α-particles is deflected through an angle greater than 90°. The most direct conclusion drawn from this rare large-angle scattering is that:

A. the electrons of the atom carry most of its mass
B. the atom as a whole is electrically neutral
C. nearly all the mass and the entire positive charge of the atom are concentrated in a tiny central region
D. α-particles are strongly attracted by the orbital electrons

Example 2 · difficulty 3/5

An α-particle with kinetic energy 5.0 MeV approaches a gold nucleus (Z = 79) head-on. Ignoring recoil, the distance of closest approach is approximately:

A. 2.3 × 10⁻¹⁴ m
B. 4.55 × 10⁻¹⁴ m
C. 9.1 × 10⁻¹⁴ m
D. 4.55 × 10⁻¹⁵ m

Example 3 · difficulty 2/5

According to the Bohr model, the radius of the first orbit of the He⁺ ion is:

A. 0.265 Å
B. 0.529 Å
C. 1.058 Å
D. 2.116 Å

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 2016 Physics Modern 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 2016 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.
