(b) If the values of the vertical distance of the centroid of the surface from the free surface
and the area of the surface are known, Dorothy claims that she can measure the
magnitude of the hydrostatic force acting on a plane surface submerged in water
regardless of its shape and orientation. Is this a valid claim? Explain.
