SUMMARY

The discussion centers on determining the buoyant force on a rigid plastic bead fully submerged in three different liquids, based on the gauge pressure versus depth plots. The buoyant force is calculated using the equation: Buoyant force = Vgd + pgA. The conclusion drawn is that as the gauge pressure (pg) and depth (h) increase, the buoyant force also increases, leading to the ranking of the plots as a > b > c, indicating that plot 'a' represents the highest buoyant force.

PREREQUISITES
  • Understanding of buoyant force principles
  • Familiarity with gauge pressure concepts
  • Knowledge of fluid mechanics
  • Ability to interpret pressure versus depth graphs
NEXT STEPS
  • Study Archimedes' principle in detail
  • Learn about fluid density variations and their effects on buoyancy
  • Explore the relationship between pressure and depth in different fluids
  • Investigate applications of buoyant force in engineering contexts
USEFUL FOR

Students studying physics, particularly those focusing on fluid mechanics, as well as educators and professionals involved in engineering and design where buoyancy plays a critical role.

Homework Statement


The gauge pressure pg versus depth h is plotted in the figure for three liquids. For a rigid plastic bead fully submerged in each liquid, rank the plots according to the magnitude of the buoyant force on the bead, greatest first.

Homework Equations


Buoyant force= Vgd + pgA------ (1)
p=pg + d.g.h ---- (2) p=pressure d=density of water g=gravity h=height from surface

The Attempt at a Solution


then as h and pg increases buoyant force increase according to equation 1. Then the highest slope represents the highest boyant. a>b>c
Is my answer correct?
