Determine if the following scientific statement is true or false:
"As a fully submerged solid iron ball sinks deeper and deeper into a deep body of water, the upward buoyant force acting on it increases drastically due to the rising water pressure."
Correct Answer
false
Explanation
While localized pressure surrounding the ball increases with depth, the difference in pressure between the top and bottom of the ball remains constant because water is virtually incompressible. Since the volume of the iron ball and the density of the water do not change, the displaced weight of water—and thus the buoyant force—remains the same at any depth as long as it is fully submerged.
