2020 F = ma Exam B — Question 15

In the device shown, blocks of various masses are placed on pistons so that the device is in equilibrium. (The fluid in the drawing is to scale.) There are valves that are both initially open at locations A and B. One of the valves is closed, and the system is allowed to come to equilibrium. How will this affect the height of the mass m2 ? m1 m2 A m3 B — Source: Question 15, 2020 F = ma Exam B, © 2020 American Association of Physics Teachers (AAPT) and the U.S. Physics Team.
