Question

Moment of inertia of a uniform circular disc of radius r and mass m about an axis touching its diameter and perpendicular to the disc is

Answer 1

I(about com) = mr²/2

According to parallel axis theorem:-
I = I(about com) + m(distance between the com
axis and the require axis)
I = mr²/2 + mr²
I = 3mr²/2


here I represents moment of inertia
