With a wooden ball and a high water tank we hold four experiments. In the first experiment we have a floating ball weighed in a vessel. In the second experiment, the ball is weighed while tied to the bottom of the vessel, the third time the ball held under water by using a thin rod, finally, during the fourth experiment the ball is taken deep inside and released. While the ball is moving up, the weight is recorded. In which case the weight recorded is more than the weight of ball + water + tank?
