A straight pipe is completely filled with stationary oil. The pipe is horizontal, and its circular cross-section is viewed end-on. In this view, point B is at the lowest point of the inner wall and point L is at the leftmost point of the inner wall.
Which statement describes the directions of the pressure forces exerted by the oil on the inner wall at points B and L?
Downwards at B and to the left at L.
Upwards at B and to the right at L.
Upwards at B and to the left at L.
Downwards at B and to the right at L.
