Given information
the shape of the vertical plate is given to be as follows:
Step-by-step explanation
Step 1.
Since the trapezoid plate is half dipped in water, the length of the trapezoid that coincides with the topmost layer of water is .
While the depth increases by 1 m, the width decreases by 1 m. So, at any depth h from the surface of water, the width w of the plate is given as follows:
So, the area of a thin horizontal strip of the plate of thickness dh at this depth h is .
The hydrostatic pressure at the depth h is . therefore, compute the force on this thin strip.
