A boat's rudder is turned by a rigid handle that rotates about a pivot. A sailor can push with the same force either close to the pivot or at the far end of the handle. At either position, the force acts at right angles to the handle.
What happens to the turning effect on the rudder when the sailor pushes at the far end rather than close to the pivot?
A smaller turning effect, because the far end of the handle moves further.
A greater turning effect, because the perpendicular distance from the pivot is greater.
A smaller turning effect, because the force acts further from the rudder blade.
The same turning effect, because the size of the force has not changed.
