Question

2. Define moment of inertia and write
the formula for ring, solid sphere and
hallow sphere?​

Answer 1

Answer:

Moment of Inertia of thin Spherical Shell or Uniform Hollow Sphere. Let M and R be the mass and the radius of the sphere, O at its centre and OX be the given axis. ... Therefore, the moment of inertia of thin spherical shell and uniform hollow sphere (I) = 2M$R^{2}$/5.

Answer 2

Moment of inertia is defined as the quantity expressed by the body resisting angular acceleration which is the sum of the product of the mass of every particle with its square of a distance from the axis of rotation
