Problem

A uniform meter stick lies flat on a table. A

4.0\,\text{N}

downward force is applied at the

20\,\text{cm}

mark. Taking the

40\,\text{cm}

mark as the pivot, what is the magnitude of the torque exerted by the

4.0\,\text{N}

force? a)

1.6\,\text{N}\!\cdot\!\text{m}

0.80\,\text{N}\!\cdot\!\text{m}

0.40\,\text{N}\!\cdot\!\text{m}

2.0\,\text{N}\!\cdot\!\text{m}
