Two students push a door open at the same point on the door, using forces of the same size. One pushes at right angles to the door and the other pushes at 45∘ 45^\circ\,45∘ to the door. Which statement is correct?
Both moments are the same, because the forces and the distances are the same
The moment is larger at 45∘45^\circ45∘, because part of the force acts along the door
The moment is larger at right angles, because the perpendicular distance is larger
The moment is larger at 45∘45^\circ45∘, because the force acts over a longer path
