Oil flows horizontally from left to right through a pipe. A flat pressure-sensor plate forms a sloping part of the pipe wall. The oil touches one face of the plate.
Four labelled arrows start at point X on the plate.
| Arrow | Direction |
|---|---|
| P | Vertically upwards |
| Q | Horizontally in the direction of the oil flow |
| R | At right angles to the plate, from the oil into the plate |
| S | At right angles to the plate, from the plate into the oil |
Which arrow shows the direction of the force caused by the pressure of the oil on the plate at point X?
Arrow Q
Arrow S
Arrow R
Arrow P
