Answer:
Moment of force is the product of magnitude of force and perpendicular distance between line of action and axis of rotation. Therefore greater the distance from the line of action to the axis of rotation, more will be the moment of force. It makes opening the door easier. Thus, handle to open the door is always provided at the free end of the door.
