A ring and a disc have same mass and same radius. The ratio of moment of inertia of a ring about a tangent in its plane to that of the disc about its diameter is

Options:

Answer:

Solution:

Moment of inertia of a ring about a tangent in its plane is given by $I = \frac{3}{2} M R^{2}$ Moment of inertia of a disc about its diameter is given by $I^{'} = \frac{1}{4} M R^{2}$ $∴ \frac{I}{I ^{'}} = 6$
