A sphere of radius 10 cm weighs 1 kg,calculate the moment of
inertia:
a)about the diameter
b)about the radius

Vaibhav T. · Accepted Answer

Dear Student,

mass, m=1 kgradius, r=10 cm=0
1 mmoment of inertia of sphere about its diameter, I=25mr2I=25×1×0
12=0 004 kgm2

Also, moment of inertia about its radius is same as about its
diameter
