A uniform thin rod of mass

3\,\text{kg}

and length

0.80\,\text{m}

is pivoted about an axis perpendicular to the rod and passing through a point

0.20\,\text{m}

away from its centre. Calculate the radius of gyration of the rod about this axis. a)

0.46\,\text{m}

0.31\,\text{m}

0.20\,\text{m}

0.56\,\text{m}
