Problem

A uniform solid disc has mass

M

and moment of inertia

I_{\mathrm{CM}}

about its central axis. The axis is now shifted in the plane of the disc by a distance

d

without changing its direction. How does the increase in moment of inertia (

\Delta I

) depend on

d

? (a)

\Delta I

is directly proportional to

d

(b)

\Delta I

is independent of

d

(c)

\Delta I

is directly proportional to

d^{2}

(d)

\Delta I

is inversely proportional to

d^{2}
