Question

The moment of inertia of a thin uniform circular diso
about one of the diameters is I. Its moment of inertia
about an axis perpendicular to the .plane of disc and
passing through its centre is
(1) √2 I (2) 2I (3) I/2 (4) I/√2

Answer 1

Answer:

Your question is not clear to understand

Answer 2

hlo mate

we know, moment of inertia of a uniform circular disc of mass M and radius R about an axis passing through centre is given by,

from perpendicular axis theorem,

moment of inertia of disc about a diameter ,

a/c to question, it is given that, moment of inertia of disc about a diameter is I

then,

so, ........(1)

now, we have to find moment of inertia about an axis perpendicular to its plane and passing through a point on its rim.

use parallel axis theorem,

so,

hence, option (c) is correct.
