A wheel of mass 15 kg has a moment of inertia of 200 kg `m ^(2)` about its own axis, the radius of gyration will be

Options

A. `3.6 m`
B. `4 m`
C. `4.6 m `
D. `1.21m`

Explanation

To find the radius of gyration \( k \) of the wheel, we can use the relationship between the moment of inertia \( I \), mass \( m \), and radius of gyration \( k \). The formula is given by:

\[ I = m k^2 \]
