Original practice preview

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

Example 1 · difficulty 2/5

According to Kepler's second law, the line joining a planet to the Sun sweeps out equal areas in equal intervals of time, so the planet moves fastest at perihelion. This law is a direct consequence of:

A. conservation of linear momentum
B. conservation of angular momentum
C. conservation of kinetic energy
D. Newton's third law of motion

Example 2 · difficulty 4/5

Planets A and B have the same mean density, but the radius of B is twice that of A. The ratio of the escape speed from B to that from A, and the ratio of acceleration due to gravity on the surface of B to that on A, are respectively:

A. 1 : 2 and 1 : 2
B. 2 : 1 and 1 : 2
C. 4 : 1 and 2 : 1
D. 2 : 1 and 2 : 1

Example 3 · difficulty 2/5

Two point masses 2 kg and 3 kg are 2 m apart. Taking G = 6.67 × 10^-11 N m² kg^-2, what is their gravitational force?

A. 1 × 10^-10 N
B. 2 × 10^-10 N
C. 4 × 10^-10 N
D. 1.67 × 10^-11 N

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 2018 Physics Gravitation 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 2018 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.
