Calculating Specific Gravity and Density of a Body

Click For Summary
SUMMARY

The discussion focuses on calculating the density and specific gravity of a body weighing 100 N in oil with a density of 0.8 g/cm³ and 60 N when immersed in water. The solution provided is 1.3 g/cm³. The participant attempted to use the formula for apparent weight, defined as actual weight minus buoyant force, but did not achieve the correct result. Detailed steps and reasoning are required to clarify the misunderstanding in the calculations.

PREREQUISITES
  • Understanding of buoyancy and Archimedes' principle
  • Familiarity with the concept of apparent weight
  • Knowledge of density calculations
  • Basic algebra for solving equations
NEXT STEPS
  • Review Archimedes' principle and its applications in fluid mechanics
  • Study the calculations for buoyant force and its impact on weight
  • Learn how to derive density from weight and volume measurements
  • Explore specific gravity and its relationship to density
USEFUL FOR

Students in physics or engineering, educators teaching fluid mechanics, and anyone interested in understanding buoyancy and density calculations.

Homework Statement



If you have a body that weighs 100 N dipped in oil that has density equal to 0.8 g / cm³. This same body when immersed in water begins to weigh 60 N. How do I find the density / specific body mass?

Homework Equations


Solution= 1,3 g/cm³

The Attempt at a Solution


Already tried using the formula of the apparent weight = actual weight - buoyant and not worked.
