Problem

A light

2.0\,\text{m}

rod is horizontal. A

40\,\text{N}

upward force is applied at

0.20\,\text{m}

from the left end, and a

20\,\text{N}

downward force is applied at

1.60\,\text{m}

from the left end. At which of the following positions, measured from the left end, should a pivot be placed so that the net torque on the rod is zero? a)

0.40\,\text{m}

1.10\,\text{m}

0.67\,\text{m}

0.80\,\text{m}
