Question

The moment of inertia of a thin circular disc about an axis passing through its centre and perpendicular to its plane is 1. Then, the moment of inertia of the disc about an axis parallel to its diameter and touching the edge of the rim is

Answer 1

The moment of inertia of a thin circular disc about an axis passing through its centre and perpendicular to its plane is 1. Then, the moment of inertia of the disc about an axis parallel to its diameter and touching the edge of the rim is 5/2L

Answer 2

The moment of inertia of a thin circular disc about an axis passing through its centre Nd perpendicular to its plane is 1. Then , the moment of inertia of the disc about an axis parallel to its diameter Nd touching the edge of the rim is 5/2L.
