PhysicsSystems of Particles and Rotational MotionMHT CET

A disc rotates horizontally at the rate of 100 r.p.m. Moment of inertia of the disc about the axis of rotation is 1 kg-m. A lump of molten wax weighing 50 gm drops gently at the distance of 20 cm from the axis of rotation of the disc and remains stuck to it. Then increase in moment of inertia of the system is

Answer: (B)

Solution

Increase in M.I. = kg m, i.e. of 1
