Question Style in MHT CET Moment of Inertia PYQs

Every question in this PDF is a single-correct MCQ. Most compare or calculate the moment of inertia of a standard body about a given axis.

Question Style	What it Tests
Ratio of moments of inertia	A solid sphere and a disc of the same radius, two rings turning about a diameter and about their own axis, and two discs of different radii
Radius of gyration	The radius of gyration of a disc, a ring, a hollow sphere and four particles at the corners of a square
Parallel and perpendicular axis theorems	A sphere about a parallel axis, a rod about its end, and a disc about a tangent
Composite bodies	Spheres connected by a rod, a disc with a hole cut out, and identical spheres or rings arranged in a hexagon
Energy and recasting	The rotational kinetic energy of a flywheel, and the moment of inertia of a sphere recast into smaller spheres

How to Use the Moment of Inertia PYQ PDF for MHT CET

Start with the 2025 and 2026 papers first, because they hold 36 of the 83 questions.
Learn the standard values: ring MR², disc MR²/2, solid sphere 2MR²/5, rod ML²/12 about its centre.
Use the parallel axis theorem for any axis that does not pass through the centre, and the perpendicular axis theorem for plates.
Solve year-wise PYQs by timing yourself, as time management is crucial.
Re-attempt only the questions you got wrong, and note which formula or step you missed.
