Question

A solid sphere of mass 10 kg, has radius 1m then its moment of inertia in kg m² about its any axis passing through its center of mass is​

Answer 1

Given moment of inertia of the wheel about its axis is 160kgm2

I=MK2 (K is the radius of gyration)

160=10×K2

K=4m

Radius of gyration of the wheel about its own axis is 4 m.
