Problem

A door

1.0\,\text{m}

wide is pushed with a constant

40\,\text{N}

force perpendicular to its surface in three situations: (i) at the handle

1.0\,\text{m}

from the hinges, (ii) at the midpoint of the door edge, (iii) at a point

0.25\,\text{m}

from the hinges. Rank the three situations in descending order of the torque produced about the hinge (largest first).
