These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 2/5
The moment of inertia of a uniform rod of mass M and length L about a perpendicular axis through one end is ML²/3. Its moment of inertia about a perpendicular axis passing through a point at a distance L/4 from one end of the rod is:
- A. ML²/12
- B. 7ML²/48
- C. ML²/16
- D. 5ML²/48
Example 3 · difficulty 3/5
A student on a frictionless rotating stool spins with angular speed ω while holding dumbbells in outstretched hands. She pulls her arms in, reducing the moment of inertia of the system to half its initial value. The ratio of her final rotational kinetic energy to the initial rotational kinetic energy is:
- A. 1 : 1
- B. 4 : 1
- C. 1 : 2
- D. 2 : 1
