Problem

A mobile consists of a light horizontal rod pivoted at its center. On the left side, a

0.25\,\text{kg}

figurine hangs

0.25\,\text{m}

from the pivot. On the right side, an identical figurine originally hung the same distance from the pivot, but it has been replaced by a

0.30\,\text{kg}

figurine at the same location, causing the mobile to tilt. Which of the following single adjustments will most effectively restore rotational equilibrium? a) Move the

0.30\,\text{kg}

figurine

0.05\,\text{m}

closer to the pivot. b) Move the

0.30\,\text{kg}

figurine

0.05\,\text{m}

farther from the pivot. c) Move the

0.25\,\text{kg}

figurine

0.05\,\text{m}

farther from the pivot. d) Move the

0.25\,\text{kg}

figurine

0.05\,\text{m}

closer to the pivot.
