Torque excerted on the support by a mass

  1. Oct 22, 2006 #1
    A 125-g mass is placed on one pan of a balance, at a point 25 cm from the support of the balance. What is the magnitude of the torque about the support exerted by the mass?

    125kg*9.81m/s^2*.25m = 306.56 N*m

    why is this wrong?

    You mixed up the units [kg] and [g].
