PhysicsSystems of Particles and Rotational MotionMHT CET

Four particles each of mass are lying symmetrically on the rim of a disc of mass and radius . Moment of inertia of this system about an axis passing through one of the particles and perpendicular to plane of disc is

Answer: (B)

Solution

Disc about a point on its rim: (1/2)MR² + MR² = (3/2)MR². The four particles are at 90°rees, at distances 0, R √2, 2R, R √2 from the axis,
