Why does the resultant force (Fr) not occur at the centroid of submerged objects? As an object lowers in water (yc increases), will the resultant force get closer to the centroid or farther away?
a) The resultant force occurs at the centroid due to buoyancy.
b) The resultant force does not occur at the centroid due to the irregular shape of submerged objects.
c) The resultant force does not occur at the centroid due to the variation in pressure with depth.
d) The resultant force does not occur at the centroid due to the gravitational pull.
