Question 35

A survey instrument is completely submerged in water. Its flat front face is vertical, and an adjacent flat face slopes upwards from left to right. Water touches both faces. The instrument is turned until the sloping face is horizontal and faces upwards.

Explain how the directions of the forces exerted by the water on the two faces compare before the instrument is turned. Then predict the direction of the force on the sloping face after it has been turned.
