The figure shows an overhead view of a meter stick that can pivot about the dot at the position marked 20 (for 20 cm). All five horizontal forces on the stick have the same magnitude. Rank those forces according to the magnitude of the torque that they produce, greatest first.



  1. τ1 > τ2 > τ3 > τ4 > τ5
  2. τ3 = τ4 > τ1 > τ2 > τ5
  3. τ1 = τ3 > τ4 > τ5 > τ2
  4. τ1 = τ3 > τ4 > τ2 = τ5
  5. τ5 > τ4 > τ3 > τ2 > τ1
