A thin circular plate of mass M and radius R
has its density varying as (r) = ₀r with ₀ as
constant and r is the distance from its centre.
The moment of Inertia of the circular plate about
an axis perpendicular to the plate and passing
through its edge is I = aMR². The value of the
coefficient a is :
