⭕ The perpendicular axis theorem states that the moment of interia of a planar body about and axis perpendicular to its plane is equal to the sum of its moment of inertia about two perpendicular axes concurrent with perpendicular axis and lying in the plane of the body.

⭕ Moment of inertia of solid sphere abou its diameter is 2 MR^2/5

⭕ Moment of inertia of sphere about tangent = 2MR^2/5 + MR^2 = 7MR^2/5
