Problem

System A consists of four particles: •

1\,\text{kg}

0.40\,\text{m}

• two particles of

2\,\text{kg}

each at

0.60\,\text{m}

•

3\,\text{kg}

0.80\,\text{m}

about a common axis. System B has three particles each of mass

2\,\text{kg}

placed at the same distance

R

from the axis. If both systems are required to have the same moment of inertia, the value of

R

should be ____. a)

0.57\,\text{m}

0.77\,\text{m}

0.87\,\text{m}

0.68\,\text{m}
