    The magnitude of the torque here is 100 newton-meters. But now take a look at diagram C. You push with 200 newtons of force at a distance of 2r perpendicular to the hinge which makes the lever arm 2r or 1.0 meter so you get this torque . Now you have 200 newton-meters of torque because you push at a point twice as far away from the pivot point.
