A horizontal cylinder contains compressed air. Its right-hand end is sealed by a flat, vertical cap.
In which direction does the pressure force exerted by the air act on the cap?
In all directions equally across the cap
To the right and upwards, at an angle to the cap
Horizontally to the right, away from the air
Towards the cylinder's centre, parallel to its axis
