Question
A wire of mass m and length is bent in the form of a circular ring, the moment of inertia of the ring about its axis is
Options
A.
B.
C.
D.ml2
Solution
Length of the wire = l
Let it is bent in the form of a circular ring of radios r. =
The moment of inertia of the ring about its axis,
I = mr2 = m ×
=
