Textbook Question
Chapter 12.2, Problem 1cT
Imagine that you were to release the block from part B at a much greater depth. Statewhether each of the following forces on the block would be greater than, less than, orequal to the corresponding force on the block in part B above:
1. the upward force on the bottom surface on the block.
2. the downward force on the top surface of the block.
3. the vector sum of the forces on the block by the surrounding water. (Hint: Does thedifference between the pressures at the top and bottom surfaces of the block change?)
The vector sum of the forces exerted on an object by a surrounding liquid is called thebuoyant force. This force is customarily represented by a single arrow on a free-body diagram.

Which force is the force you measure with the spring scale?arrow_forwardI am having trouble ranking these four blocks. The answer key says: Least C < D < A < B Greatest but I can't figure out how to solve it to get that answer. Consider the same four blocks (A-D) which are all more dense than the fluid. Rank, from smallest tolargest, the time for the blocks to reach the bottom of the container (tA , tB , tC , and tC ). You may findit helpful to draw free body diagrams and use Newton’s laws for each block. If any of the situations haveequal times, clearly indicate this in your ranking.
