2.0\,\text{kg}

uniform thin rod of length

1.0\,\text{m}

is to be rotated about an axis perpendicular to the rod and located a distance

d

from its center. The desired rotational inertia about this axis is

0.35\,\text{kg}\cdot\text{m}^2

. Which value of

d

best meets this requirement? (a)

0.46\,\text{m}

(b)

0.30\,\text{m}

(c)

0.22\,\text{m}

(d)

0.37\,\text{m}
