Force on the bottom of the vessel containing a submerged cube

Click For Summary

Homework Help Overview

The discussion revolves around a physics problem involving a tank of water and a submerged metal cube. The original poster describes a scenario where the cube is lowered into the tank, and there is a need to analyze the readings from a spring balance and an electronic scale as the cube descends. The problem involves understanding the forces acting on the system, including buoyancy and the weight of the water.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants explore the relationship between the readings of the spring balance and the electronic scale, questioning the assumptions about the forces involved. There is confusion regarding the correct expression for the scale reading and the impact of the cube on the water level.

Discussion Status

Some participants have offered insights into the relationship between the buoyant force and the weight of the water, while others are questioning the accuracy of the answer key. The discussion is ongoing, with various interpretations being explored regarding the forces acting on the system and how they relate to the readings from the instruments.

Contextual Notes

There is a noted ambiguity in the definitions of the variables, particularly concerning the distance 'h' and its implications for the readings. Participants are also discussing the potential for misinterpretation of the problem statement and the graphical representations required.
